Question

I will give you extra point and mark you braniest if you give me an explanation on how to find the answer.

Answer 1

Explanation:

You simply use the formula for the area of a cylinder.

Answer 2

Explanation:

The surface area of a cylinder is 2pi *rh + 2pir^2, where r and h are radius and height, respectively. (If you want me to explain this, comment down below). Anyways, we can simply plug in 11 and 8 in the formula, so 2* 8*11*pi + 2* pi * 8^2=304pi. Thus, we do 304 * 3.14=954.56.
