Question

Quarry shaped like a cone has a height of 42 ft and a diameter of 48 ft.

What is the volume of the quarry?
Use 3.14 to approximate pi, and express your final answer in hundredths.

_____________ ft3

Answer 1

Volume of cone = (1/3)*(height)*(pi)*(radius)*(radius)

height = 42
radius = diameter / 2 = 48 / 2 = 24
pi = 3.14

Volume of this Cone = (1/3)*(42)*(3.14)*(24)*(24)
= 25320.96 ft3
