Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. Apply the second equation to get π x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters).
This calculator will calculate the area of a circle given its diameter, using the famous formula area = pi times (d/2) squared. It supports different units such as meters, feet, and inches.
The area of a circle formula using radius is: Area = π x r 2; The area formula using diameter is: Area = π x (d/2) 2; Use online calculators for quick, accurate area calculations; Finding circle areas is useful for many real-world applications; Practice calculating areas, diameters and radii using the formulas

To use this formula, simply square the radius of the circle and multiply it by π to obtain the area. For example, if the radius of a circle is 5 units, the area of the circle would be: A = πr² = π (5²) = π (25) = 78.5 square units. So, the area of a circle with a radius of 5 units would be approximately 78.5 square units. Using Diameter.
