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?

x2

2x

Ax?

х

EX

12

11 / 42. *. X^ 2. * X = I/3 X A * h; if E = 1/3 A

Then the answer is EX

Step-by-step explanation:

Volume of cone = 1/3 * base area * height

= 1/3 * pi * (X/2) ^2 * X

= 1/3. * 22 / 7 * X^3/4

= 22 / 21 * X^3 / 4

= 11/21 *. X^2 / 2. *. X

= 11 / 42. * X^3

= 11 / 42. *. X^ 2. * X
