What is the volume of a cone with a diameter of 20 cm and a height of 15 cm? Use 3.14 for pi.

Question

O 314 cubic centimeters
O 1,570 cubic centimeters
O 6,280 cubic centimeters
O 2,355 cubic centimeters

Answer 1

The formula for the volume of a cone is V = 1/3πr^2h, where r is the radius and h is the height.

First, we need to find the radius of the cone. The diameter is 20 cm, so the radius is half of that, which is 10 cm.

V = 1/3 * 3.14 * 10^2 * 15
V = 1/3 * 3.14 * 100 * 15
V = 1/3 * 3.14 * 1500
V = 0.3333 * 4710
V = 1570 cubic centimeters

Therefore, the volume of the cone is 1,570 cubic centimeters.

Therefore, the answer is:
O 1,570 cubic centimeters
