Question

What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?

Answer 1

Hello! The formula for the volume of a cone is πr^2h1/3. That means the volume of the cone is 1/3 of the base (squared radius * height * pi). The radius is 2 inches. 2^2 is 4. The height is 3 inches. 4 * 3 is 12. Pi is an irrational number that repeats, but we can use 3.14 as pi. 12 * 3.14 is 37.68. Keep in mind that this is an answer choice, but it is not the answer. We have to divide that by 3 to find the actual area, because the area of the cone is 1/3 of the base. 37.68/3 is 12.56. There. The volume of the cone is 12.56 cubic inches. The answer is A.
