Introduction

In mathematics, a cylinder is a three-dimensional shape that consists of two parallel and circular bases connected by a curved lateral surface. The volume of a cylinder is a fundamental concept in geometry and is used in various real-world applications, such as architecture, engineering, and design. In this article, we will explore the formula for finding the volume of a cylinder and provide a step-by-step solution to calculate its volume.

What is the Volume of a Cylinder?

The volume of a cylinder is the amount of space inside the cylinder. It is measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³). The volume of a cylinder depends on its radius and height. The formula for the volume of a cylinder is:

V = πr²h

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
  • h is the height of the cylinder

How to Find the Volume of a Cylinder

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

Step 1: Identify the Given Values

  • r (radius) = 4 cm
  • h (height) = 10 cm

Step 2: Plug in the Values into the Formula

  • V = πr²h
  • V = π(4)²(10)

Step 3: Calculate the Square of the Radius

  • (4)² = 16

Step 4: Multiply the Square of the Radius by the Height

  • 16(10) = 160

Step 5: Multiply the Result by π

  • 160(3.14) = 502.4

Step 6: Calculate the Volume

  • V = 502.4 cm³

Example 2: Finding the Volume of a Cylinder with a Different Radius and Height

Suppose we have a cylinder with a radius of 6 cm and a height of 15 cm. To find its volume, we can use the same formula:

  • V = πr²h
  • V = π(6)²(15)

Step 1: Calculate the Square of the Radius

  • (6)² = 36

Step 2: Multiply the Square of the Radius by the Height

  • 36(15) = 540

Step 3: Multiply the Result by π

  • 540(3.14) = 1703.2

Step 4: Calculate the Volume

  • V = 1703.2 cm³

Conclusion

In this article, we have explored the formula for finding the volume of a cylinder and provided a step-by-step solution to calculate its volume. We have also used two examples to demonstrate how to apply the formula in different scenarios. By following these steps, you can easily find the volume of a cylinder and apply this concept in various real-world applications.
