Question 744088: I have to find the diameter of a pizza to the nearest tenth of an inch with this given info. "A large circular pizza is divided into 10 equal slices (sectors). Measuring along the outer edge of the crust for one piece, only, you find it to be 5.25 inches long. What is the diameter of the large pizza to the nearest tenth of a inch?"
