   If you are given the diameter (which is twice the radius) then you would need to divide the diameter by 2 to get the radius and the use the formula A = πr 2. Example: Find the area of a circle with a diameter of 8 units. Use 3.14 for π. Divide the diameter by 2 to get the radius. Radius = 8 ÷ 2 = 4. A = πr 2 = (3.14) (4) 2 = 50.24 units 2.
