Calculating the Area of a Circle | A Step-by-Step Guide with Example Calculation

Area of circle

The area of a circle can be calculated using the formula A = πr^2, where A represents the area and r represents the radius of the circle

The area of a circle can be calculated using the formula A = πr^2, where A represents the area and r represents the radius of the circle.

To find the area of a circle, follow these steps:
1. Measure the radius of the circle. The radius is the distance from the center of the circle to any point on its edge.
2. Take the value of the radius and square it (multiply it by itself).
3. Multiply the squared radius by the mathematical constant pi (π), which is approximately 3.14159.

Here’s an example to help illustrate the process:

Let’s say we have a circle with a radius of 5 units.
To find its area:
1. Square the radius: 5^2 = 25.
2. Multiply the squared radius by π: 25 x 3.14159 = 78.53975.

Therefore, the area of the circle with a radius of 5 units is approximately 78.54 square units.
