The circumference of circle P is 62.8 inches, and the diameter is 20 inches. What expression represents an approximation for pi?
Pi by definition is simply the ratio C/D = pi where C = 62.8 in and D = 20 in. Plug in the numbers and you can get a value out as far in decimal points as you wish. And that's pi, not an approximation of pi.

Tape measure to find the circumference and the diameter of a place. The circumference was 35 and the diameter OS 11. Find the number of diameter in the circumference.?
11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
