Question

Find the surface area of the cylinder. Round your answer to the nearest hundredth.

A. 569.26 in2
B. 724.34 in2
C. 795.45 in2
D. 1,707.77 in2

Answer 1

C. 795.45 in^2

Explanation:

The formula for the surface area of a cylinder is ...

SA = 2πr^2 +2πrh = 2πr(r +h)

For r=6 and h=15.1, the surface area is ...

SA = 2π(6)(6 +15.1) = π(12)(21.1) = 253.2π

SA ≈ 795.45 . . . . square inches
