1 point extra: The material for the tent is $1.50 per sq ft. Find the price of the material to make the tent.

Answer 1

sorry not Draw
R=6 H=6

Answer 2

Ok, so where are you stuck now?>

Answer 3

i don't know how to break it down do i do SA = 2*pi*r*r + 2*pi*r*

Answer 4

that's a formula for a AREA OF THE WHOLE CYLINDER right?

Answer 5

yes.?

Answer 6

And what you are given in the equation is HALF of a cylinder.
So what if we find the area of a WHOLE cylinder and Divide it by 2 to get half of it?

Answer 7

oops yes!*

Answer 8

got it?

Answer 9

kk so i have to Divide it by 2 with R=6 H=6?? sorry i'm trying to understand it

Answer 10

It's okay. dont worry. i aint gonna get annoyed by questions..

Nope, so that formula was for the whole cylinder, something like,

But in the question you are given half of it, something like,

Answer 11

So we will assume that we have to find the area of a whole cylinder and divide it by 2 later to get the area of the half of the cylinder..

Answer 12

kk this look wrong but is it like this?

L=2
L=2x6(6)
L= 12(6)
L=72
????

Answer 13

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

2*pi*(6)*(6) + 2*pi*(6)*(6)

Answer 14

OHHHH okay! thank you... i can do the other one thank u so much!

Answer 15

Dont forget to divide the final answer by 2.

Cheers! :D

Answer 16

lol thanks!! CHEERS XD!
