How do you find the diameter with the area?

Divide the area (in square units) by Pi (approximately 3.14159). Take the square root of the result (Example: 310.56). This is the radius. Now double the radius to get the diameter (Example: 621.12 meters).

Is radius half the diameter?

A radius is half the length of the diameter.
