Area of a circle
A=pi*(r^2)
The area of a circle can be calculated using the formula:
A = πr²
where A represents the area of the circle, r represents the radius of the circle, and π (pi) is a constant value approximately equal to 3.14.
To calculate the area of a circle, square the radius value and multiply by pi.
For example, if a circle has a radius of 5 cm, the area would be:
A = πr²
A = π(5 cm)²
A = π(25 cm²)
A = 78.5 cm²
Therefore, the area of a circle with a radius of 5 cm is 78.5 square centimeters.
