Question

Oscar wants to fill with water a bucket that is the shape of a right circular cylinder. It has a 6-inch radius and12-inch height. He uses a shovel that has the shape of a right circular cone with a 3-inch radius and 4-inch height. How many shovelfuls will it take Oscar to fill the bucket up level with the top?

Answer 1

Answer: I think it is 36 shovelfuls

Explanation:

V = πr²h

V = π • 6² • 12

V = π • 36 • 12

V = 1357.2in³

V = 1/3πr²h

V = 1/3 • π • 3² • 4

V = 1/3 • π • 9 • 4

V = 1/3 • π • 36

V = 37.7in³

1357.2 ÷ 37.7 = 36 shovelfuls
