pi * 2 * square root(256 / pi) = 56.7185232 inches
Area of a circle in square inches = pi*radius2 in inches
If the circle has a diameter of 8 inches, it's 50.265 square inches. If the circle has a radius of 8 inches, it's 201.06193 square inches. In the odd case that the circle has a circumference of 8 inches, it's 5.09296 square inches.
9.628874057 square inches rounded to two decimal places is 9.63 square inches.
The radius of the circle is 21 inches. The area of the circle is (pi) times (radius squared) = pi times 441 = 1,385.44+ square inches. 1 square foot = 144 square inches. The area of the circle is (1385.44+ square inches) divided by 144 = 9.621 square feet (rounded to 3 decimal places).
256*pi square inches Area of a circle = pi*radius2
Circumference = Pi x D Area = Pi x r2 D = 2r Thus area = Pi x 2.552 = 20.4 inches2
Approx 1146 square feet.
