The formula for circumference is Pi x D= Circumference. If you know the circumference you solve for the diameter as you would any other variable. Let's say the circumference is 10, the equation would then be: Pi (3.14) x D = 10. Solve for D.
D= 10/3.14

What is the circumference of a 5 foot table?
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
What is the circumferance of a seven eighths inch circle?
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
What is the circumference of a 7 feet diameter circle?
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.
How do you get the radius from the circumference?
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 what is the diameter?
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.
How do you change circumferance into diameter?
circumference/pi = diameter
How do you work out the circumferance if the diameter is 100mm?
circumference = pi*100mm
What is the diameter of a circle with a circumferance of 60 meters?
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
To measure the circumferance of a circle with a known diameter?
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
What is circumferance if diameter is 14 inches?
Circumference = (pi) x (diameter) = 14 pi = 43.9823 inches (rounded)
What is the circumferance of a circle that has a diameter of 27?
What is 27 X 3.14? 27 pi
If the circumferance of circle is 13 ft what is the diameter?
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
What is the Circumferance of 8' diameter circle?
Just over 25' ( 8 x pi)
What is diameter of a 130mm circumferance?
Circumference equals Diameter times Pi, OR Diameter equals (Circumference)/(Pi). In this case, Diameter equals (130mm)/(Pi or 3.14159) equals 41.38mm
If the diameter of a baseball is 3 inches what is the circumference?
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.
What is the diameter if a circle measures a circumferance of 39 inches?
39 inches / pi = 12.4 inches
