- What is the relationship between the volume of a sphere and the volume of a cylinder when both examples have the same diameter and height?
- Write a formula for the volume of a sphere. Use the formula for the volume of a cylinder.
- The height of the cylinder is twice the radius of the sphere, or h = 2r. In the formula you determined in question 2, substitute the value 2r in for h. Simplify the formula.
