The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

Suggestion: Divide the circumference by (2 x pi) to get the radius. Then use the standard formula for the area of a circle.

The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.

Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.

4*pi*r2. because surface area is equal to circumference of circle.

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

The formula for the circumference of a circle is: radius (x) 3.14 (pi) Area is... Radius2 x 3.14

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.

Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.

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 formula for the circumference of a circle is 2πr, where r is the radius. We can rearrange this formula to solve for the radius: r = circumference / (2π) = 9.42 / (2 * 3.14159) = 1.5. Then, using the formula for the area of a circle (πr^2), the area is π * 1.5^2 ≈ 7.07 square units.

It isn't. That is the formula for the AREA of a circle!

You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in the formula for the circumference: C = 2 pi r. Then you can calculate the circumference of the circle by multiplying pi times twice the radius.
