The distance around the crater is 9415. If the crater is in the shape of a circle then this distance is the circumference of the circle. The circumference C and diameter D of a circle are related by the formula

C = PI * D

If you plug in 9415 for C and 22/7 for PI and solve for D you get

9415 = (22/7) * D

D = (7/22) * 9415 ~ 2995.7
