Question

What is the surface area of the Right Cylinder below
Diameter AB=22, and height BC=8.

Answer 1

A ≈ 1313.19

Explanation:

By using the formula
`A = 2 \pi r h + 2 \pi r^(2)` we can just fill in the information with what we know, which is Diameter = 22, Radius = Diameter/2 = 11. The height is 8. So in doing so we get
`A = 2\pi (11)(8)+2\pi (11)^(2)`, which
equals ≈
`1313.18573`.
