Answer 1

any idea ?

Answer 2

this 4sqrt3 is correct

Answer 3

thats apart of the question though

Answer 4

yes but what is the next step ?

Answer 5

you need calcule area of these two lateral sides what are squares

Answer 6

in case of pup tent

Answer 7

how you calcule area of a square ?

Answer 8

side x side

Answer 9

yes exactly so how many will be ?

Answer 10

so 8 x 8

Answer 11

wait

Answer 12

yes 8 x 8

Answer 13

yes what is equal how many ?

Answer 14

64

Answer 15

ok but 64 two time

Answer 16

bc. there are two sides with this area

yes ?

Answer 17

128

Answer 18

yes so 128 is area of these two lateral sides and now what you need calcule again to get the total surface area of tun ?

Answer 19

of pup sorry

Answer 20

you ve calculed the altitude of triangle

why ?

Answer 21

V = (1/3)AH is the formula

Answer 22

so i assume i plug this in

Answer 23

but you dont need calcule the volume of these

Answer 24

this 4sqrt3 is the altitude of this triangle from the front

so how you calcule area of this triangle ?

Answer 25

8x8 again but you half the result, in otherwords 1/2bh

Answer 26

so if 8x8 is 64 you do 64/2 in which its 32?

Answer 27

please answer my question

Answer 28

im new to this so im sorry in advance if i dont know certain steps. thats why i would like an explantation

Answer 29

you need calcule the surface area of every t

Answer 30

of every two figure

Answer 31

we begin with area of pup tent

Answer 32

above you ve get the lateral area with area of these two sides the form of square

yes ?

Answer 33

ok

Answer 34

and now you need calcule again area of these two triangles from the front and in the back

Answer 35

but you see that area of these triangles are equale

so please calcule area of a triangle

Answer 36

32

Answer 37

no

how you calcule area of a triangle ? formula ?

Answer 38

Area of Triangle = (1/2)(ab)

Answer 39

so use this and make the calcule

Answer 40

area = ?

Answer 41

i am literally getting 32.
0.5x8x8=32
unless im missing something crucial this is what its saying

Answer 42

please make it step by step how i ve wrote above

area of this triangle for what you know the altitude

Answer 43

area triangle = altitude time base divide 2

a = ?

Answer 44

a = 4sqrt3 × 8 /2 = ?

Answer 45

16
√
3

Answer 46

is what ive gotten

Answer 47

a = 16sqrt3

Answer 48

yes so but there are two triangles so you need multiply this by two

yes ?

Answer 49

ok

Answer 50

so 16sqrt3 *2?

Answer 51

yes equal how many ?

Answer 52

32sqrt3

Answer 53

sure

and now you need assuming area of these two lateral sides and area of these two triangles

Answer 54

so total surface area - this is area without area of the base - yes ?

Answer 55

ok

Answer 56

ok please assume what i ve wrote above

Answer 57

these two areas of these two lateral sides we ve calculed first of all - please check it above

Answer 58

128 for the lateral sides and 32sqrt3 correct?

Answer 59

yes assume these

Answer 60

so total surface area of pup tent = 128 +32sqrt3

and now you need calcule surface area of tunnel tent what is a cylinder halfed

Answer 61

ok

Answer 62

please calcule it

Answer 63

how you calcule it ?

Answer 64

2πr^2+h(2πr)?

Answer 65

this is the surface area formula of a cylinder

but you have a halfed cylinder

Answer 66

just you need divide this formula by 2

Answer 67

hmm give me a moment for that one

Answer 68

2π*2r ?

Answer 69

no

2pir^2 + h×2pir

(2pir^2 +2pir×h)/2 = ?

Answer 70

courage this is easy

Answer 71

from inside parantheses factoriz out the 2 and simplify it with 2 from denominator

yes ?

Answer 72

ok

Answer 73

please than make it

Answer 74

bc. you need calcule it in number

Answer 75

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9
no

2pir^2 + h×2pir

(2pir^2 +2pir×h)/2 = ?
\(\color{#0cbb34}{\text{End of Quote}}\)


(2pir^2 +2pir×h)/2 = 2(pir^2 +pir×h)/2 = pir^2 +pir×h so this is surface area of this halfed cylinder

Answer 76

using that foruma ive gotten 64pi

Answer 77

assuming the x is the * symbol

Answer 78

× is the multiply symbol there

Answer 79

ok

Answer 80

oh wait ive read the last part wrong

Answer 81

pir^2 + pirh =

r = 4
h = 8
pi = 3,14

3,14 *16 + 3,14 *4 *8 = ?

Answer 82

150.72

Answer 83

and then we have to round that to the nearest hundreths

Answer 84

still 150.72.

Answer 85

ok

and now for you can answering this question of your exercise you need checking what surface is greatest

yes ?

Answer 86

in otherwords which needs the most nylon required in the least?

Answer 87

and the least*

Answer 88

yes but first you need getting what surface is greatest

Answer 89

total surface area of pup tent = 128 +32sqrt3

total surface area of halfed cylinder = 150,72

Answer 90

the pup tent is the greatest

Answer 91

yes exactly bc. just than you assume the 128 with 32 you get 160 what is greater than 150

Answer 92

yes

Answer 93

so and now what will be the right correct answer on this question of your exercise ?

Answer 94

the tunnel tent

Answer 95

yes sure

so do you understand it now ?

Answer 96

yes. and ill save all your explantions so it will help me in the future.

Answer 97

i thank you for taking your time with my non functioning brain
