Cylinder Volume Worksheet With Answers And Examples

Quick Links :

The study of cylinders is an essential part of mathematics, particularly in geometry and trigonometry. Cylinders are three-dimensional shapes that have two parallel and circular bases connected by a curved lateral surface. Understanding how to calculate the volume of a cylinder is crucial in various real-world applications, such as engineering, architecture, and physics.

What is the Volume of a Cylinder?

The volume of a cylinder is the amount of space inside the cylinder. It can be calculated using the formula:

V = πr^2h

Where:

• V is the volume of the cylinder
• π (pi) is a mathematical constant approximately equal to 3.14
• r is the radius of the cylinder's circular base
• h is the height of the cylinder

How to Calculate the Volume of a Cylinder

To calculate the volume of a cylinder, you need to know the radius and height of the cylinder. Here's a step-by-step guide:

1. Find the radius of the cylinder's circular base.
2. Find the height of the cylinder.
3. Plug the values of the radius and height into the formula V = πr^2h.
4. Calculate the volume by multiplying the values and solving for V.

Cylinder Volume Worksheet Examples

Here are some examples of cylinder volume worksheets with answers:

Example 1:

Find the volume of a cylinder with a radius of 4 cm and a height of 10 cm.

Solution:

V = πr^2h = π(4)^2(10) = 3.14(16)(10) = 502.4 cubic centimeters

Example 2:

Find the volume of a cylinder with a diameter of 8 cm and a height of 15 cm.

Solution:

First, find the radius of the cylinder:

Radius = diameter/2 = 8/2 = 4 cm

Then, calculate the volume:

V = πr^2h = π(4)^2(15) = 3.14(16)(15) = 753.6 cubic centimeters
