The equation for the circumference of a circle, or the total distance around a circle, is pie times circumference. so all you need to do is multiply 27 inches times pie (or 3.14). for more information about circles and equations here is a site.

The perimeter or circumference of a circle is given by the formula Pi*d ,where pi=3.14 and d is the diameter of the circle
Hence circumference=3.14*27
=84.78 inches

The formula for the circumerence (C) of a circle if you know the diameter (d) is:
C = pi * d
C = pi * 27
Therefore
C = 84.82 inches
.

circumference=pie (multiply) diameter
so try to multiply this= 27 (multiply)22 (over) 7=84.85714286
(approximated=85 inches)

okay, the formula is Circumference=pie*diameter, so it would be 27pie, or about 84.78
