WebFeb 2, 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm diameter in the calculator. The results should also be 50.265 cm and 201.06 cm². Other awesome Omni Calculators WebMay 24, 2024 · Explanation: You need to know the formula for calculating the area of a circle: πr2 So if you know that the diameter is 5 ft, you can calculate the radius. The radius the measurement in a circle from the middle to an outer edge: this means that r = d 2 So therefore, 5 2 = 2.5f t Now we can calculate the area using the formula. 2.52 = 6.25
