Math, microeconomics or criminal justice
diameter = about 17.8'
Circumference of a circle =C= 56' = 56 feet
= pid = pi times the diameter
= about 3.141593 x d
C=pi(d)
divide both sides by pi
C/pi=d
d=C/pi
d =about 56/3.141593 = 17.82535363...
pi is an irrational number with a nonrepeating decimal sequence, about 3.14 as the often used approximation or 22/7 which =about 3.14285...
diameter = about 17.8 feet
= longest distance across the circle
= the length across the circle that cuts it exactly in half
if you used pi = 22/7
then d=C/pi = 56/22/7 = 56(7/22) = 28x7/11 = 196/11 =17.818181... = about 17.8'
