Circumferance = pi x diameter of the circle If your table is 5 ft in diameter, then the circumference is : pi x 5 ft = 15.71 ft
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
The circumference of a 7 feet diameter circle is: about 21.99 feet.You can easily to this calculation for other circles by multiplying the diameter by Pi (about 3.1416). The result is the circle's diameter.
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.
If a circle has a circumference of 6 ft, the diameter is: about 1.91 feet. You can easily do this calculation for other circles by dividing the circumference by Pi (about 3.1416). The result is the diameter.
circumference/pi = diameter
circumference = pi*100mm
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
Either pi times the diameter or pi times twice the radius (which is the diameter)
Circumference = (pi) x (diameter) = 14 pi = 43.9823 inches (rounded)
What is 27 X 3.14? 27 pi
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Just over 25' ( 8 x pi)
Circumference equals Diameter times Pi, OR Diameter equals (Circumference)/(Pi). In this case, Diameter equals (130mm)/(Pi or 3.14159) equals 41.38mm
The circumferance is found by using the formula 2(r)(pi). r stands for the radius. The diameter, which is already given in the problem, is two time radius. Therefore the only thing you really have to do is multiple the diameter= 3 inches by pi. Circumferance is 9.425 inches.
39 inches / pi = 12.4 inches
