To find the area of a circle, you need to use the formula:
Area of circle = π x (radius)^2
where π (pi) is a mathematical constant approximately equal to 3.14159, and the radius is the distance from the center of the circle to any point on the edge of the circle.
how to find the circumference of a circle
Here are the steps to find the area of a circle:
1. Measure the radius of the circle. If you don't have the radius, you can also use the diameter, which is the distance across the circle passing through the center, and divide it by 2 to get the radius.
2. Square the radius (multiply it by itself).
3. Multiply the squared radius by pi (Ï€). You can use 3.14159 as an approximate value for pi.
4. Round your answer to the desired level of precision, if necessary.
Area of circle = π x (radius)^2
For example, if the radius of a circle is 5 cm, then its area would be:
Area of circle = π x (5 cm)^2
Area of circle = 3.14159 x 25 cm^2
Area of circle ≈ 78.54 cm^2
