Area of a circle is a mathematical concept that refers to the total space inside a circle. It is calculated by multiplying the radius of the circle by itself and then multiplying that number by pi. The area of a circle is important in many areas of mathematics, including geometry, trigonometry, and calculus.

A Area of a Circle Calculator is a tool used to calculate the area of a circle. It takes the radius of the circle as an input and calculates the area of the circle based on the formula A = πr2.

To calculate the area of a circle, use the formula A = πr2, where r is the radius of the circle and π is approximately equal to 3.14. The radius is the distance from the center of the circle to any point on the circumference.
