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.

diameter x pi

It is: 10*pi

It is the distance around a circle and is found by 2*pi*radius or diameter*pi

The formula is pi multiplied by the diameter

find the circumferance as if it was a whole circle but when you get the answer divide it by 2

radius = circumference/2*pi

C = 75.4 inches

The circumference is approximately 37.7 yards.

36/pi = 11.4591559 inches

Diameter of circle: 13/pi = 4.138 ft to 3 decimal places

Circumference of circle: 14*pi = 43.982 feet rounded to 3 decimal places

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

Circumference of circle: 14*pi = 43.982 feet rounded to 3 decimal places

Length of the outside edge of a curve; for circle C=6,28 r.

Just over 25' ( 8 x pi)

39 inches / pi = 12.4 inches

What is 27 X 3.14? 27 pi

19 pi, ie 19 x 3.1415 = 59.69

Approx 1146 square feet.

30/pi = just over 9.5 cm

Either pi times the diameter or pi times twice the radius (which is the diameter)

I am not sure if it is called a circumference, since it is not a circle, but whatever it is called is 583,400,000 miles in length.

circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.

Yes. It is similar to the distance of a circumferance of a circle and its radius.
