The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².

In a circle with a diameter of 4, there would be approximately 12.56 square inches in the circle.

diameter = 8 inches so the radius will = 4 inches area of a circle = pi*radius2 area = 50.26548246 or 50 square inches to the nearest square inch.

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

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

The area of a circle is the number pi (3.14159...) times the square of the radius. The radius is half the diameter. So if the diameter is 8 inches, the radius is 4 inches. Squaring that gives us 4 x 4, or 16 square inches. Multiplying 16 by pi equals an area slightly larger than 50.26 square inches.
