Area = pi*92 = 254.469 square feet to 3 decimal places
Remember the circle equation. A = pi r^(2) A = 3.141592.... (9ft)^2 = A = 3.141592... 81sq.ft A = 254.4690049... sq.ft. ~ 254.5 sq.ft.
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
Area = pi*92 = 254.469 square feet to 3 decimal places
the circumfrence of a circle is pi times it's radius squared.
