Question

What is the surface area of a cylinder with a base radius of 3 ft and a height of 5ft

Answer 1

SA of a cylinder: 2$\pi$r² + 2$\pi$rh
r = radius of base
h = height of cylinder

Plug in 3 for r and 5 for h in the formula.
2$\pi$3² + 2$\pi$(3)(5)
Use a calculator to solve.

2$\pi$3² + 2$\pi$(3)(5) = 150.8 ft²
