A circle with an area of 100.53 square units has a circumference of 35.542 units.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
Circumference : 94.2 meters Area : 706.5 square meters
Radius = square root of (area/pi) Circumference = 2*pi*radius
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
A = 0.785 square units.
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
circumference about 28.27 inches area about 63.62 square inches
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
Circumference = 2Pi times the square root of the(area divided by Pi)
