If 60 ft is the diameter then,
Circumference= pi X dia
=3.14 X 60
=188.4 feet

The circumference (or perimeter of a circle) formula is
C = 2(pi)radius or C = 2(pi)r where r = radius of circle.
The radius od a circle is half the diameter of the circle:
(1/2) diameter = radius
(1/2) 60 feet = 30 feet
Since r = 30 feet, then
C = 2(pi)(30 feet)
C = 60(pi) feet
pi is the ratio of the circumference to the diameter of any circle. pi is approximately 3.14.
C = 60(3.14) feet
C = 188.4 feet

circumference = πd
d= 60 ft
circumference = (3.1416)*60 ft
circumference = 188.5 ft.

circumfrence = pi x diameter
circumfrence = pi x 60
=3.141582 x 60
=188.5 feet (to 1dp)
