The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
diameter = circumference/pi = 12/pi inches
12 inch diameter(also 6 inch radius).
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
diameter = circumference/pi = 12/3.1416 units = 3.62 units (approx)
The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
Circumference = 37.7 inches Diameter = 12 inches
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
The formula for working out the circumference of a circle (like a pipe) is diameter times pi. (You should find pi on your calculator, if not, it is 3.14159265) Since you know the circumference, you divide the circumference (5inch) by pi (3.14159265), and you get the diameter, i.e. the size pipe. While the above formulas are correct, using this equation example will not tell you what size pipe you have. There are a number of factors involved in determining the correct answer. There are many different materials that pipe is made out of and some of these affect the dimensions of the pipe. As an example, the actual outside diameter of 1" copper pipe and 1" steel pipe are not the same. If you are talking about steel pipe, it is important to understand that all pipe 12 inch and under is referred to as "nominal" pipe size. In this case, the outside diameter of 12 inch pipe is actually 12.75 inches. For the original question asked above, the 5 inch circumference would equal 1-9/16" outside diameter which would be the equivalent of 1-1/4" pipe (nominal).
12 inch diameter(also 6 inch radius).
diameter = circumference/pi = 12/pi inches
12 inch diameter(also 6 inch radius).
A 12-inch diameter circle has a circumference of: 37.7
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).Circumference of a circle is pi x diameter, pi has a value of 3.1415, can you proceed from here, you can do it, try it, Good luck!
12/pi inches, about 3.5 inches
If a pipe is 12 inches aroud, then that is its circumference. The width is the diameter. To get the diameter, you'll have to divide 12 by pi, or 3.14, and the answer you get is 12/3.14=3.82.
Circumference = pi * diameter.C = 3.14159 * 12C = 37.69908 inches
