Area of the circle = (circumference)2 / (4 pi)
Area = 0.0796 circumference2(rounded)
The circumference is: 32.1
The area of a circle when the circumference is 10 inches is: 7.96 square inches.

To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
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
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
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.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
If the object is a circle and if 24 is the diameter, the area is 452.39 and the circumference is 75.4
