Area = pi*r2 = 2*pi*r = circumference
then r2 = 2r so that r = 2

The radius of the circle works out as 5 units in length
The radius of a circle is defined as the distance from the centre-point to the circumference.
The circumference is the perimeter of a circle. Basically the length of the outside of a circle. Circumference=2*pi*radius
It's the circle's radius which extends from its center to its circumference and it can be of any length you want it to be.

Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
Circumference = 2*pi*radius = 189.75 units of length.
2*pi*radius
the radius
The radius of a circle is defined as the distance from the centre-point to the circumference.
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.
Circle has a circumference and a diameter, what is meant by length, I wonder
The circumference is the perimeter of a circle. Basically the length of the outside of a circle. Circumference=2*pi*radius
