Diameter = 314/pi feet
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
Using 3.14 as Pi the area of circle is: 314.0
you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
Using pi as 3.14 it works out that the diameter is 20 cm

Diameter = 314/pi feet
Larry Shaw made pi day on 3, 14, 1989.
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 100 feet, so the circumference would be C = π(100) = 314.159 feet.
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm
Divide 314 by pi and square root the answer which will give you the radius.
A= pi r squared 3.14 * 10 *10 = 314 square feet.
It is: the square root of (314/pi) = 9.997 units to 3 dp
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
Using 3.14 as Pi the area of circle is: 314.0
