Well, darling, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 8 inches, the radius would be half of that, which is 4 inches. Plug that into the formula, and you get an area of 16π square inches. Voila!
The area of a circle with an 8 inch diameter is: 50.27 square inches. There are: pi*4 squared = 16*pi square inches or about 50 square inches
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
The circumference of a circle whose diameter is 8 inches is about 25.13 inches.
