Question

need help, picture shown. help pleasee

Answer 1

with all?

Answer 2

well, with what you want to help me with. my teacher gave this to me, and half the class doesnt understand it.

Answer 3

wat r we solving for the surface area right?

Answer 4

yeah

Answer 5

i have done the first one.

Answer 6

1.B

Answer 7

lol i had that one

Answer 8

2.A

Answer 9

how did you get 2?

Answer 10

3.C

Answer 11

ok ill explain

Answer 12

thank you(:

Answer 13

you c that the pyramide is made up of a hexagon and 6 triangles each triangle is the same so wat u do is find the area of 1 and multiply it by 6. Are u with e so far?

Answer 14

yeah

Answer 15

gud now to find the area of the hexagon you have to picture it being made up of 6 triangles with each triangle sharing 1 of its sides with a side of the hexagon.u see the imaginary triangles?

Answer 16

yeah

Answer 17

gud we can now find the area of 1 triangle and multiply it by 6. then add the areas of the triangles with the hexagon and then u have the surface area of the triamide

Answer 18

It's not very clear and I am guessing at some of the numbers. Based on the answers, you must find the surface area. For #1. The triangle on left has height 11.7 to the base 9. Area=(1/2)*9*11.7. There are two of each triangle. So multiplying by 2, the area is9*11.7=105.3.
For the triangle on the right, Area=(1/2)*12*11. Two of these also, so area is 11*12=132.
The rectangle's area is 12*9= 108
Adding all the areas: 105.3+102+108=total area=315.3 square units

If it's lateral area, don't add the area of the rectangle.

Answer 19

okay lol, thanks for explaining it . and how do i find area of one triangle?

Answer 20

the area of a triangle is base (6)x height (5.2) all over(divided by) 2

Answer 21

do you want to know a fun fact about triangles? it explains y this is the way to find the area of a triangle

Answer 22

so you have to find the area of the triangle first, then multiply it by the number of base sides. t hen divide it by 2?

Answer 23

Area=basexheight/2
and since the triangle is the same as the other 6 (which is the amount of sides in the hexagon) that y u multiply by 6 after u divide by 2.(though it really doesnt matter which goes 1st IN THIS CASE)

Answer 24

so why is there a 11.3?

Answer 25

11.3 is the height of the triangles that stretch out from the hexagon and is used to find there areas. 5.2 is the height of the imaginary triangles that make up the hexagon and is also used to find the area of the hexagon

Answer 26

oh.. well how did you get 297?

Answer 27

u dont understand?

Answer 28

do i do both of them, like 11.3*6 and 5,2*6. then add the answer up.

Answer 29

.. sorry to waste your time..

Answer 30

ohh!

Answer 31

i got it

Answer 32

i just happy that u care about knowing cause there r a lot of people who just want answer :)

Answer 33

explain it then

Answer 34

just to make sure

Answer 35

so..
11.3*6+5.2*6=99
then divite it by 2 and times that by 6.

Answer 36

wrong order
6(11.3*6/2) + 6(5.2*6/2)=297

Answer 37

therefore 6* area of an above triangle + 6* area of a triangle that make up the hexagon =297

Answer 38

soo what i did was wrong? cuz i did it on a calculator and i got 297. im just wondering cuz if i cant do that, i dont want to do it for another problem and get it wrong.

Answer 39

ur way shows that u dont understand cause everything is mixed up and doesnt follow the formulae for the area of a triangle so for an other question it probably wont be right.

Answer 40

Oh, well alright ill write yours down. do you think you have enough time to show me a few more, or at least # three

Answer 41

yes

Answer 42

try doing # 3

Answer 43

I did but i couldnt.. thats why i asked if you had time for more.

Answer 44

yea its more confusing alright then

Answer 45

i dont really know what the formulas are. i think thats one of my biggest problems.

Answer 46

can we review #2 one last time though?

Answer 47

yeah for sure

Answer 48

ok 1st lets find the area of one triangle do that and show me the working and answer

Answer 49

what area do i need to find first?

Answer 50

you can find any first i just chose the triangles on top the hexagon but if u want we can find for the hexagon first it doesnt matter.

Answer 51

well, you have to times it by the number of sides first, so thats why it starts out as 6, and then i would multiply the base * height. which is 11.3*6. and then divide it all by 2. so it would be, 6(11.3*6/2) then you need to find the other part, and that would be 6(5.2*6/2) and yeah. do i have it?

Answer 52

wait

Answer 53

oh, so 6(11.3*6/2) is the triangle. and 6(5.2*6/2) is the hexagon

Answer 54

1 step at a time all i want is thearea of 1 triangle ull c just now y im slowing it down

Answer 55

not all just 1

Answer 56

but isnt the 6 at the beginning all 6 triangles

Answer 57

that isnt a formula i made that up as a short cut. the only formula here is for the area of 1 triangle

Answer 58

use the formula which is A=base*height/2

Answer 59

:/ oh. so i use that, then multiply it by the number of base sides

Answer 60

forget multiplying by the number of base sides

Answer 61

then what do i do..because if i can barely do this one, how can i do ones that are harder

Answer 62

i just dont know my formulas for anything, and the steps

Answer 63

crsnetime focus this is the formula Area=base*height/2 do you know wat the base and the height is? if so then plug it in and solve for the area that is it ill get to wat comes next after

Answer 64

the base is 6, and the height is 11.3 and 5.2.. right

Answer 65

and dont warry when im done with u u will be the smartest in the class for this topic

Answer 66

base=6 and height=11.3

Answer 67

i know that part

Answer 68

whats after that?

Answer 69

u didnt tell me wat the area is yet

Answer 70

203.4?

Answer 71

fyi there is no formulae that solves all the sides u can only solve each side of the figure at a time till u find them all for each question

Answer 72

ohh. thats alot of work

Answer 73

6*11.3/2=203.4? wat kinda calculator r u using?

Answer 74

oh did (11.3*6/2)6

Answer 75

yesso in tests leave these questions for last

Answer 76

tell me wat is the formula for the area of a triangle?

Answer 77

b*h/2

Answer 78

exactly there r no 6s in that formula so dont add a 6 to it. now tell me wat is the area of theat triangle andshow me working

Answer 79

11.3*6=67.8
67.8/2=33.9

Answer 80

correct now we r on the same page :)

Answer 81

yay!!

Answer 82

I have a question..

Answer 83

now u just found the area of only 1 triangle and luck for us all the other triangles r identicle so what we do is add them 6 times 33.9 + 33.9 + 33.9 + 33.9 + 33.9 + 33.9 or u can take a short cut and do this instead 33.9*6. Do u c y we multiply by 6 now?

Answer 84

it has nothing to do with the sides of the hexagon. So now work out 33.9*6 and give me your answer

Answer 85

33.9*6=203.4

Answer 86

would you consider being a tutor? or is that to much to ask

Answer 87

yea ill tutor u when i got time :)

Answer 88

ahhhh thanks! youve just been alot of help. how would i be able to get back to you?

Answer 89

can i get ahold of you on this site?

Answer 90

click on my name and then click become a fan

Answer 91

so the trick for this topic is to be able to break up the figure in to shapes and find there areas indevidually

Answer 92

can you tell me all the formulas you know for different shapes

Answer 93

hello? we rnt finished though

Answer 94

i know.. sorry

Answer 95

so did u multipy 33.9 by 6 yet?

Answer 96

oh and tell me y 6?
