How to find the area of a circle with the radius?

The area of a circle is the amount of space enclosed within the boundary of a circle.

Answer: The Area of a circle with the radius is given by the formula πr².

The distance from the centre of the circle to a point on the boundary is called the radius of a circle. It is represented by the letter "r".

Explanation:

The area of a circle with the radius is given as:

Area of a circle = πr²

Thus, the area of a circle is given by πr².
