find the circumferance as if it was a whole circle but when you get the answer divide it by 2
radius = circumference/2*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.
C = 75.4 inches
It is the distance around a circle and is found by 2*pi*radius or diameter*pi
The circumference of any circle is the irrational number "pi" (very approximately 3.1418) times the diameter of the circle.
What is 27 X 3.14? 27 pi
The circumference is approximately 37.7 yards.
36/pi = 11.4591559 inches
7/8 inch circle has a diameter of 7/8 and a radius of 7/16=.4375 circumferance of a circle = 2*pi*radius = 2*3.14*.4375 =2.7475 or 7*pi/8
