The LessonThe volume of a cylinder is found using the formula:
In this formula, r is the radius of the cylinder and h is the height of the cylinder. The image below shows what we mean by the radius and height:

How to Find the Volume of a Cylinder
QuestionWhat is the volume of a cylinder with a radius of 5 cm and a height of 10 cm, as shown below?
Substitute the radius and the height into the formula. In our example, r = 5 and h = 10.
Volume = π × 52 × 10
Volume = π × 5 × 5 × 10
Volume = π × 250
Volume = 3.14 × 250
Volume = 785 cm3
