Best Answer

Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)

The circumference is: 32.1

If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm

You dived the area by the circumference of the circle.

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).

Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)

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.

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.

Area of the circle = (circumference)2 / (4 pi)Area = 0.0796 circumference2(rounded)

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

To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).

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.
