How Do You Find the Volume of a Sphere?
The formula for the volume of a sphere is volume equals four-thirds pi times the radius cubed. That's a mouth-full. But if you are given the radius value of the sphere, all you have to do is plug it in and do the arithmetic. Just remember to use the order of operations.

How Do You Find the Volume of a Cone?
The formula to find the volume of a cone is volume equals one-third times the base times the height. The base can be found by using the formula to find the area of a circle: base equals pi times radius squared. So it seems that the area of the base needs to be found to solve for the area of a cone.

What is Circumference?
There are actually two formulas to find the circumference of a circle. One formula is based on knowing the diameter of the circle, and the other is based on knowing the radius of the circle. The instructor illustrates both formulas. She plugs in the known values and solves each equation to show how they come up with the same solution.
