1. Measure the radius and multiply it by itself (square it)
2. Multiply Pi (3.14159....) with answer of step 1.
That will be the area.
Area of circle = Pi x radius2
Radius = Half the diameter of the circle.

Area of circle = pi*(radius)2
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
The area of a circle is measured in square units. The formula is: pi*radius2
No because the formula for finding the area of an oval, which is an ellipse, is quite different
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
