Calculating Circle Area: A Step-By-Step Guide With Formula And Examples Including Pi’S Role.

Area of a Circle

P = 4(s)

The area of a circle is the amount of space inside the circle. It can be calculated using the formula A = πr², where A represents the area, π represents the mathematical constant pi (approximately 3.14), and r represents the radius of the circle.

To find the area of a circle, you can follow these steps:

1. Measure the radius of the circle. This is the distance from the center of the circle to any point on the edge of the circle.

2. Square the radius (multiply it by itself).

3. Multiply the squared radius by pi. This will give you the area of the circle.

For example, if the radius of a circle is 4 inches, the area can be calculated as follows:

A = πr²
A = π(4)²
A = π(16)
A ≈ 50.24 square inches

Therefore, the area of the circle with a radius of 4 inches is approximately 50.24 square inches.
