Solved Examples on Area of a Circle Calculator
Example 1: If a circle has a radius of 5 meters, the area can be calculated using the formula:
Area = π × radius × radius.
Area = π × 5 × 5 = 25π square meters.
Example 2: We have a circle with a diameter of 10 feet. First, we find the radius by dividing the diameter by 2, which gives us a radius of 5 feet. Now, we use the formula:
Area = π × radius × radius again.
Area = π × 5 × 5 = 25π square feet.
Example 3: A circular swimming pool with a diameter of 6 meters. To find its area, we start by finding the radius (which is half the diameter), so the radius here is 3 meters. Using the formula:
Area = π × radius × radius
Area = π × 3 × 3 = 9π square meters
