Area of a circle with a diameter of 8?
50.2656 square inches The formula to find the area of a circle is ∏r2. Where ∏ is the mathematical constant and r is the radius of the circle. So 3.14 x 42. = 50.27 square cm or yds, (whatever the diameter was in).

How do you find the area of a circle if all you have is the circumference?
The formula for the area of a circle is pi(r2)...ie: 3.14xr2 The circumference is pi(diameter) and the radius (r) is half of the diameter (d) Example...if the circumference is 25.12in then the area is 50.24in Work being... Circumference = 3.14(d)=25.12 To find the diameter you have to get d by itself... Divide 3.14 to both sides to do that 3.14/3.14(d)=25.12/3.14 d=8 Now that you have the diameter you know that the radius is half of the diameter so radius (r)=4 Therefore the area of the circle is 3.14(42)=50.24in
