Circle Area
A=πr²
The area of a circle is the amount of space contained within the circular shape. The formula for finding the area of a circle is A = πr^2, where A is the area, π (pi) is a mathematical constant that can be estimated as 3.14, and r is the radius of the circle.
To find the area of a circle, you need to know its radius. The radius is the distance from the center of the circle to any point on the edge. Once you know the radius, you can use the formula above to calculate the area.
For example, if the radius of a circle is 5 inches, the area would be:
A = πr^2
A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 square inches
Therefore, the area of the circle with a radius of 5 inches is 78.5 square inches. Remember to include the units when giving the answer.
