Remember the circle equation .
C = pi d
d = 4.6
pi = 3.141592.....
C = 4.6 X 3.1241592.... = 14.45192.... cm
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The circumference of any circle is (pi) x (the circle's diameter).
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
