The base diameter and the height of a cone are both equal to x units. Which expression represents the volume of the cone, in cubic units? πx2 2πx3 πx2 πx3

The volume of a cone is expressed as one third of the product of pi, square of the radius and the height which is written as:

V = (1/3) πr²h

since d and h is x and d is equal to 2r.

V = (1/3) π (x/2) ² (x)

V = (1/3) π (x²/4) x

V = πx³/12 units³
