The area is 314 cm2

10 feet.

You have to use the equationcircumference is equal to the radius multiplied by "pi" multiplied by twoC = 2 * π * rBecause your circumference is a known value, the only unknown value left is the radius. Simply solve the equation.314 / (2*π) = rr = 50.0 feet

Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.

Divide 314 by pi and square root the answer which will give you the radius.

10 feet.

3.14*r*r=area 3.14*100=314 or 100pi

I'm assuming you mean the following:--------|OOO||OOO||OOO|--------Where:Each circle touches, but does not overlap, each adjacent circleThere is no gap between the edge of the circles and the edge of the squareThe area of each circle is 314 units2Let r be the radius of a circleThe area of a circle is pi x r2r = square root of (314 / pi)r = approx*. 10 unitsThe length of each side of the square = 6 x r = approx*. 60 units* approximate, because the value of pi is not exactly 3.14

Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
