The height of the cone is 9 cm and the diameter of the base is 36 cm, find the volume of the cone.

Knowing the diameter of the base of the cone, we determine its radius.

R = OA = D / 2 = 36/2 = 18 cm.

Calculate the volume of the cone using the formula:

V = n * R ^ 2 * h / 3, where R is the radius of the circle at the base of the cone, h is the height of the cone.

V = n * 18 ^ 2 * 9/3 = n * 972 cm3.

Answer: The volume of the cone is n * 972 cm3.
