Question

The distance around a meteor crater is 9,014 ft. Find the diameter of the crater. Use 22 7 for π.

Answer 1

9890/pi = 9890/22/7 = 9890(7)/22 = about 3146.8 feet

Circumference = pi(d) where d= diameter

d = C/pi = 9890/(22/7) = 9890(7)/22 = 69230/22 = 3146.818181... or 3146 18/22 = 3146 9/11 feet

if you used a more precise value for pi, 3.14159, you'd get closer to 3148 feet
