Question

A cylindrical barrel is 8 feet tall, and 5 feet wide at the bottom. What is the volume of the barrel?

Answer 1

V = 50π ft³

Explanation:

That "5 ft wide at the bottom" translates into "radius of (5/2) ft."

Volume of a cylinder of radius R and height H is V = πR²H, so here,

V = π(5/2)^2*8 ft³ or

V = π(25/4)(8) ft³, or

V = 50π ft³

Answer 2

The Volume is 157.04 ft.
