Answer 1

Celina is buying fabric scraps to make koozies for her glasses. Each glass is cylindrical with a diameter of 4 inches and a height of 8 inches. The koozies will cover only the sides of the glasses. What is the amount of fabric she will use? What does this amount represent? Use three point one four for pi. Show your work.

Answer 2

sup

Answer 3

We are trying to find the lateral area of cylinders, do you know how?

Answer 4

so the glass is a cylinder. You want to cover the sides area. Area of the side is 2*pi*r*h. Diameter equals to 2r, so r is 1.5 inches. therefore if you plug the numbers in you get 37.68

Answer 5

The formula is:
\[la = 2\pi r^{2}\]

Answer 6

did i do that right @jcpd910

Answer 7

Almost, the formula requires r^2, not height. Close though! :D

Answer 8

ugh

Answer 9

agh its confusing

Answer 10

So: 2 * 3.14 * 4 = 25.12

Answer 11

SA= 2(area of the bases +area of the side)
= 2(area of the circles + area of the rectangle)
=2 {[ 2(pi d^2)/4] + lw}
= 2{[2(3.14)(4^2)/4] +(4)(8)}
=114.24 sq. inches
Its not ^

Answer 13

You are solving for the surface area my friend. :D

Answer 14

And, wait, that's way off.

Answer 15

lol sorry

Answer 16

lmao yea idek what im thinking now

Answer 17

No but we were both wrong, derp.

Answer 18

I was solving for the circumference or something dorky

Answer 19

Sorry to confuzzle you >_<

Answer 20

so what would it be lol

Answer 21

37.68, he was right.

Answer 22

I just derped up and made a mess of things.
