How much bigger is a volume of a cone with a radius of 13 feet and a height of 21 feet than a cone with a radius of 7 feet and a height of 21 feet? Use 3.14 for pie

Answer 1

To find the volume of a cone, you can use the formula V = (1/3)πr^2h, where r is the radius of the cone and h is the height of the cone.

For the cone with a radius of 13 feet and a height of 21 feet:
V1 = (1/3) * 3.14 * 13^2 * 21
V1 = (1/3) * 3.14 * 169 * 21
V1 = (1/3) * 3.14 * 3549
V1 = 3706.06 cubic feet

For the cone with a radius of 7 feet and a height of 21 feet:
V2 = (1/3) * 3.14 * 7^2 * 21
V2 = (1/3) * 3.14 * 49 * 21
V2 = (1/3) * 3.14 * 1029
V2 = 1077.94 cubic feet

Therefore, the volume of the cone with a radius of 13 feet and a height of 21 feet is:
3706.06 - 1077.94 = 2628.12 cubic feet

So, the cone with a radius of 13 feet and a height of 21 feet is 2628.12 cubic feet bigger than the cone with a radius of 7 feet and a height of 21 feet.
