Best Answer

Pretty easy. First, divide the circumference by Pi (about 3.1416). The result is the diameter. Since the radius is 1/2 the diameter, divide the diameter by two to get the radius.

find the radius of a circle with circumference of 42.1

A circle with a radius of 8 inches has a circumference of 50.27 inches.

To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159

The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.

The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.

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 the equation would be pi multiplied by diameter, or radius squared. the answer would be 31.415 units squared.

For a circle, circumference = 2 x pi x radius.

Circumference of a circle = 2*pi*radius

The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.

The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.

Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.

Circumference of a circle = 2*pi*radius Circumference = 2*pi*5.6 = 35.18583772 units

the way you find the circumference is 2xpixr or pixdiameter. so it would be 2x80xpi
