Question

What is the surface area of this cylinder?

A. 384 π cm^2

B. 128 π cm^2

C. 1204 π cm^2

D. 256 π cm^2

Answer 1

ANSWER

A.

$TSA=384\pi {cm}^{2}$

EXPLANATION

The total surface area of a cylinder is given by the formula,

$TSA=2\pi \: {r}(r + h)$

We substitute the radius, which is

$r = 8cm$

and

height

$h = 16cm$

into the formula to obtain,

$TSA=2\pi \: {8}(8 + 16)$

$TSA=16 \times 24\pi$

$TSA=384\pi {cm}^{2}$

The correct choice is A.
