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.

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.

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

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 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.

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

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

Circumference of a circle = 2*pi*radius or diameter*pi

Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared

Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
