Question

What is the volume, in cubic feet, of a cone that has a base area of π / 4 square feet and a height of 3 feet?

A. 94π

B. π

C. 34π

D. 14π

Answer 1

`The\ volume\ of\ a\ cone:V=(1)/(3)B\cdot H\\\\B=(\pi)/(4)ft;\ H=3ft\\\\therefore\\\\V=(1)/(3)\cdot(\pi)/(4)\cdot3=\boxed{(\pi)/(4)\ (ft^2)=(1)/(4)\pi\ (ft^2)}`
