Question

Surface area of cylinder

Answer 1

The answer is C.
`256\pi`
`in^2`.

Explanation:

To solve for the surface area of this cylinder, start by using the cylinder surface area formula, which is
`SA=2\pi rh+2\pi r^(2)`. Next, plug in the information given from the problem into the formula, which will look like
`SA=(2)(\pi )(8in)(8in)+(2)(\pi )(8in^(2))`. Then, simplify the equation, which will look like
`SA=(128in)(\pi) +(128in)(\pi)`. The next step is to simplify the equation further, which will look like
`SA= 256\pi`
`in^(2)`. The final answer is
`256 \pi`
`in^2`.
