You can put this solution on YOUR website! Pi is a represented by 3.1416 it goes on and on 3.1415926535898... We often only use 4 digits of precision. So anytime you see pi think 3.14 or 3.1416.
The formula to find the circumference of a circel is pi*d.
So c=(pi)16
c=16(pi)
or in decimal format,
approx = 50.27 inches
