Key concepts
3 concepts
- 1
The volume of a cylinder is found using the formula πr²h, where r is the radius and h is the height.
- 2
The volume of a cone is ⅓ the volume of a cylinder with the same radius and height, using the formula V = ⅓πr²h.
- 3
The formula to find the volume of a sphere is V = 4/3πr³, where r represents the radius of the sphere.
