The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle or any two points on the circle as long as they are exactly 180 degrees apart. This tool will calculate the diameter of a circle from the area and will convert different measurement units for area and diameter. The given end points of the diameter are 24 - 2 4 and 48 4 8.

Its just twice as long. A Circle area. Diameter Cp Note. If you dont have the radius or the circumference divide the area of the circle by p and then find that numbers square root to get the radius.
