Question

A cone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?

Answer 1

The volume of a cone is:

V=(hπr^2)/3, where h=height and r=radius

V=(7π4^2)/3

V=112π/3 ft^3

V≈117.29 ft^3 (to nearest hundredth of a cubic foot)

Answer 2

117.29ft³ ....................................
Pi x 4 x 4 x 7 : 351.85830 divide by 3 : 117.29 when rounded
