What is the area of a 14 cm circle?
Let’s assume it’s equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm . You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² . Finally, you can find the diameter – it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm .
