### How do you figure the diameter of a circle from its circumference?

The circumference = pi x r2, and the diameter = 2r. So if you start with the circumference, you divide that number by pi (3.1416), then take the square root. What's left is the value of the circle's radius; double it to get the diameter.

### What do you if you divide the circumference of the sun by its diameter?

If you divide the circumference of the sun by its diameter you will have found the number called "Pi". The actual number is an infinite string of digits that starts 3.14159.
