Circumference of circle: 14*pi = 43.982 feet rounded to 3 decimal places
it is the circumfrance of a circle divided by pi.
diameter x pi
It is: 10*pi
The circumferance of a circle is equal to 2 x pi x r, where r is the radius, i.e. approximately 6.2832 than its radius. Divide the circumferance from the figure above to get the radius of a circle in which the circumferance is known.
The circumference of a circle, if its diameter is 5.1mm, is about 16.02mm
diameter = 128/pi
The formula is pi multiplied by the diameter
C = 75.4 inches
It is the distance around a circle and is found by 2*pi*radius or diameter*pi
circumference = pi*40cm
