Question

geometry

Answer 1

what is the question?

Answer 2

i have a lot actually

Answer 3

Do you know how to use eulers formula?

Answer 4

not really

Answer 5

ok

Answer 6

thats why i need so much help im currently failing geometry....

Answer 7

V - E + F = 2

Answer 8

oh
lol thats not it xd one sec

Answer 9

ah ha

Answer 10

i was gonna say idk what F is haha

Answer 11

F+V = E+2

Answer 12

faces + vertices = edges + 2

Answer 13

X+15 = 24+2 which also is equal to x=11

Answer 14

ohhhh

Answer 15

hope that helps :)

Answer 16

yeah

Answer 17

willing to help me with more?

Answer 18

sure

Answer 19

well what shape is the cross section? The shaded area?

Answer 20

pentagon

Answer 21

Hexagon, 6 sides

Answer 22

i meant that lol

Answer 23

xD

Answer 24

wait thats it?

Answer 25

ok any other questions?

Answer 26

yeah

Answer 27

ok, Lateral area is perimeter * height

Answer 28

Surface area is lateral area + 2*the area of the base

Answer 29

so the perimeter is 17+17+5+5 which equals 44

Answer 30

let me try and figure it out hold on

Answer 31

44 times the height 3.12 is equal to 137.28

Answer 32

so L.A. is 137.28 Now for the surface area

Answer 33

since i have to take notes lol one sec

Answer 34

So the Surface area is LA + 2 times the area of the base. the area of the base is 5*17 which equals 85. So the surface area is 137+(2*85) or 307

Answer 35

hows that and lol sorry I didn't see your other comments xD

Answer 36

wait would it be A or C

Answer 37

so C

Answer 38

oh okay

Answer 39

137 and 307

Answer 40

i see

Answer 41

anything else? I like helping people:)

Answer 42

youre actually making this easier

Answer 43

same exact concept just different numbers

Answer 44

okay

Answer 45

so the base is gonna be 3+9+9.49

Answer 46

times the height 37

Answer 47

where did the 9.49 come from

Answer 48

the triangle side of the prism, use that as the base

Answer 49

ohhhh

Answer 50

with triangle prisms that is the base

Answer 51

i got 795.13

Answer 52

for the surface area? or the lateral area

Answer 53

cuz that is the correct lateral area

Answer 54

the base? i think

Answer 55

the perimeter of the base times the height remember so (3+9+9.49)*37 is LA

Answer 56

oh okay ok ok lol

Answer 57

lol its fine I got confused about it when I was learning :)

Answer 58

for the SA i got 702....and ik thats not right

Answer 59

SA is LA+2*(the area of the base)

Answer 60

so the area of the base is 1/2 * 9*3=13.5

Answer 61

13.5*2=27 27+LA=822.13

Answer 62

you are helping me so much!!!!

Answer 63

:)

Answer 64

ok new formula this time :)

Answer 65

oh no...

Answer 66

lol its fine

Answer 67

2pi*r*h+2pi*r^2

Answer 68

so plug in the numbers

Answer 69

oh I guess it is the same formula, just translated into circles.

Answer 70

but still 2*3.14*12*17=1281.12

Answer 71

2*3.14*12*12=904.32

Answer 72

thats what i got!
yay

Answer 73

lol
my numbers are conflicting one sec

Answer 74

so I guess its 1282 hmm

Answer 75

i have no clue what to do here

Answer 76

ok

Answer 77

I can do 1 more then I have to go :( But I hope I helped you :)

Answer 78

ok

Answer 79

SA of a pyramid is LA+B where B is the area of the base

Answer 80

so LA is 1/2 * perimeter of the base * slant height

Answer 81

ugh this is difficult....

Answer 82

daaang

Answer 83

they are making you do a LOT

Answer 84

i know

Answer 85

ok so first you must find the side length of the base

Answer 86

my brain is done. I might just stop for the day.

Answer 87

ok side length is 15

Answer 88

1/2 * 7.5*sqr3*15 = 97.4278579257

Answer 89

eh xD yeah this will take FOREVER to do

Answer 90

well good job with everything tho :)
