Area of a circle
A=πr² where r is the radius of the circle
The area of a circle is given by the formula:
A = πr^2
where A is the area of the circle, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.
To calculate the area of a circle, square the radius of the circle and multiply by π. For example, suppose we want to find the area of a circle with a radius of 5 centimeters. Then we can use the formula as follows:
A = πr^2
A = π(5 cm)^2
A = 78.5398 cm^2
Therefore, the area of a circle with a radius of 5 centimeters is approximately 78.5398 square centimeters.
