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 calculate the area, 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 circumference.
2. Square the value of the radius. This means multiplying the radius by itself (r * r).
3. Multiply the squared radius by the mathematical constant π, which is approximately equal to 3.14159.
4. The resulting value is the area of the circle.
For example, if the radius of a circle is 5 units, the area can be calculated as:
A = π * 5^2
= 3.14159 * 5 * 5
= 3.14159 * 25
≈ 78.53975 square units
So, the area of the circle with a radius of 5 units is approximately 78.53975 square units.
