Calculation of the Area of a Circle

To calculate the area of a circle, you need to know the radius (R) of the circle. The formula for calculating the area of a circle is:

S = π * R^2

where S represents the area of the circle and π is a mathematical constant approximately equal to 3.14159.

Let's calculate the area of two circles with different radii:

1. Circle with a radius of 2 cm: - R = 2 cm - Using the formula, we can calculate the area: S = π * R^2 = 3.14159 * 2^2 = 3.14159 * 4 = 12.56636 cm^2.

2. Circle with a radius of 6 cm: - R = 6 cm - Using the formula, we can calculate the area: S = π * R^2 = 3.14159 * 6^2 = 3.14159 * 36 = 113.09724 cm^2.

Therefore, the area of a circle with a radius of 2 cm is approximately 12.57 cm^2, and the area of a circle with a radius of 6 cm is approximately 113.10 cm^2.
