Area of a Circle
A= pi r^2
The area of a circle can be calculated using the following formula:
A = πr²
where A is the area of the circle, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.
To find the area of a circle, first measure the radius of the circle. Then, square the radius and multiply it by pi to find the area. For example, if the radius of a circle is 5 units, the area can be calculated as follows:
A = π(5)²
A = 3.14159 x 5²
A = 3.14159 x 25
A = 78.53975
Therefore, the area of the circle is 78.54 square units (rounded to the nearest hundredth).
