Divide the area by Pi to get the diameter.
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
Using 3.14 as Pi the area of circle is: 28.259999999999998
4 * 3 * 3.14 = Fish
The area of a circle with a diameter of two cm is about 3.1416 cm.
