Question

A food manufacturer stores corn oil in a right circular cylindrical container. This container has a height of 12 inches, and a base whose diameter is 8 inches.
What is the surface area of this container in terms of pie

Answer 1

Use the surface area formula for a cylinder! 2πrh+2πr2

Plug in what you know! (If the diameter is 8, then that means the radius is 4.)

r = 4

h = 12

2π(4)(12) + 2π(4)(12) = 402.12

I hope this helps! :)
