Joshua is going to mow lawns during his summer break. The graph in the figure shows a linear relationship between the number of

The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference. It is calculated as follows:
C = 2pi(r)
From this, we can solve for r and evetually solve for the diameter.
