A crater shaped like a cone has a height of 24 yd and a diameter of 72 yd.

What is the volume of the crater?

Use 3.14 to approximate pi and express your final answer in hundredths.

yd3

The formula for the volume of a cone is (1/3) * area of the base * height. The base is a circle, whose area is pi times radius^2. Here this is pi * (r^2) = 3.14 * (72 / 2 yd) ^2 = 4069.44 yd^2. And so the volume is (1/3) * 4069.44 yd^2 * 24yd = 32,555.52 yd^3. I recommend that you find the most common formulas of the geometrical figures and make a flashcard that you can use at any moment.
