How to Find the Volume of a Cylinder
Question
What is the volume of a cylinder with a radius of 5 cm and a height of 10 cm, as shown below?
Step-by-Step:
2
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
Answer:
The volume of the cylinder with a radius of 5 cm and a height of 10 cm is 785 cm3.What Is a Cylinder?
A cylinder has two ends that are circles that are parallel to each other and are joined by a curved surface.A Sphere in a Cylinder
If a sphere is placed in a cylinder, the volume of the sphere is exactly two-thirds the volume of the cylinder.
Can you work out why?
A Cone in a Cylinder
If a cone is placed in a cylinder, the volume of the cone is exactly a third of the volume of the cylinder. Can you work out why?
