Question

A cone has a height of 20 millimeters and a radius of 8 millimeters. What is its volume?

Use r = 3.14 and round your answer to the nearest hundredth.

Answer 1

Explanation:

volume of cone =1/3 πr²h=1/3×π×8²×20=1280/3 π mm³

=1280/3×3.14

≈1339.73 mm³

Answer 2

Explanation:

the volume of the cone:

V=3.14*r^2*(h/3)

V=3.14*8*8*(20/3)=200.96*(20/3)=1339.73
