Question

What is the surface area of a cylinder with base radius 2 and height 6?

Answer 1

SA = 2πrh + 2πr²         radius(r) = 2     height(h) = 6

SA = 2π × 2 × 6 + (2π × 2²)

SA = 2π × 12 + (2π × 4)

SA = 24π + 8π

SA = 75.36 + 25.12

SA = 100.48        << your answer

hope this helps, God bless!
