The formula for finding the circumference is:
circumference= pi x diameter
The diameter is approximately 3,918 miles.
Pi is approximately 3 (it’s pi to the nearest whole number)
So an estimate for the circumference is:
pi x diameter = circumference
3 x 3918 = 11754
So the estimate for the circumference of the Earth is approximately equal to 11754 miles (i think)
