Question

Surface Area of Cylinder=2πrh+2πr2

Where r is the radius of the cylinder and h is the height of the cylinder. Find the surface area when r is 3 inches and h is 5 inches.

A. 112π in²
B. 48π in²
C. 80π in²
D. 50π in²

Answer 1

Answer: B. 48 pi in^2

Explanation:

Plug the given values into the equation.

So the SA = 2*pi*3*5 + 2*pi*3^2

SA = 30pi + 18pi

SA = 48 pi in^2
