            • Calculating the area of a circle using its diameter and radius is a straightforward process. The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. However, many people find it easier to use the diameter, which is twice the radius. In this case, the formula becomes A = π(d/2)^2. For example, if the diameter is 10 cm, the area would be A = π(5)^2, which equals approximately 78.5 square centimeters.
