fine the circumference of 12 inches. using 22/7 for pi

Question

using 22/7 for pi in stead of 3.14  how does that answer compare for the same diameter?

Answer 1

Circumference = Pi * Diameter

Diameter = Circumference / Pi

If we use 3.14 for Pi, we get 12 / 3.14 = about 3.822 for the diameter.

If we us 22/7 (about 3.1428) for Pi, we get 12 / (22/7) = about 3.8181 for the diameter.

If we use 22/7 instead of 3.14 for Pi, we're using a larger value for Pi and getting a smaller result (3.81 vs. 3.82) for the diameter.
