Best Answer

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

The area of a circle when the circumference is 10 inches is: 7.96 square inches.

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
