Sample Problem 1 What is the volume of a cone with a height of 12 inches and a radius of 5-
inches?



Answer :

To find the volume of a cone, you can use the formula V = 1/3 * π * r^2 * h, where: - V represents the volume of the cone. - r stands for the radius of the base of the cone. - h is the height of the cone. Given the height (h) is 12 inches and the radius (r) is 5 inches, you can substitute these values into the formula: V = 1/3 * π * (5)^2 * 12 Here's how you can solve it step by step: 1. Calculate the square of the radius: (5)^2 = 25 2. Multiply the square of the radius by the height: 25 * 12 = 300 3. Multiply the result by π (pi): 300 * π ≈ 942.48 cubic inches Therefore, the volume of the cone with a height of 12 inches and a radius of 5 inches is approximately 942.48 cubic inches.
