70.9 square inches.
Area of a circle = (1/2 x diameter)2 x piArea of a 24 inch diameter circle:(12 inches)2 x 3.1416 = 144 square inches x 3.1416 = 452.4 square inches
There are approx 4071.5 square inches.
Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet
what i do is square it 30x30 = 900 devide it by 100 and x it by 78.5398 =706.858278.5398% is correct for doing it this way.(78.5398163397425)Improved answer:Area of a circle = pi*radius2Area = pi*152 = 706.8583471 square inches
