Area, Radius, Diameter, Circumference The Area of a circle is πR² ie. 22 / 7 x Radius². The area of a circle is the space contained within the circumference and is measured in square units. The Radius is the distance from the center of the circle to the circumference. Radius = √(Area / π) ie. the square root of the area divided by PI.This problem is known as the primitive circle problem, as it involves searching for primitive solutions to the original circle problem. It can be intuitively understood as the question of how many trees within a distance of r are visible in the Euclid's orchard , standing in the origin.
