If the area of a circle is 201.06 then the circumference of the circle is?

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*pi)


What is the formula to find the circumference of a circle with the raduis given?

Circumference of a circle: 2 x pi x radius.


The circumference of a circle is 132cm what is the radius of the circle in centimeters?

To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.


How do you find the radius of a circle when the circumference is given?

Divide the circumference by the value of Pi, then halve that result.


What is the radius of a circle of a circumference of 121?

To find the radius of a circle with a circumference of 121, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.
