Question

Which is the surface are of the right cylinder below?

A. 176 pi units^2
B. 144 pi units^2
C. 192 pi units^2
D. 72 pi units^2

Answer 1

=176 pi units^2

Explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi rh where r is the radius and h is the height

= 2 * pi * 8^2 + 2 pi *8*3

= 128pi + 48 pi

=176 pi units^2
