  • How to find the distance around a circle?

    Ok I'm sure this will sound like a dumb question but I'll ask any way. Does any one know the formula for finding the circumference of a circle. I know part of it but I cant remember it all. I would be really greatfil for any help with this one. Thanks

    danomal,
    I think to keep this simple you want to take the “diameter” x “3.14”.... this should be what you are looking for. You can carry the 3.14 out further for more precision but it is probably not necessary with a tape measure... You will also need a decimal chart to convert to a fraction...

    Example: “D” (12") x “Pi” (3.14) = 37.68" or about 37-11/16" for a 12" circle...

      If your have a circular object to measure, you can lay a string on the circumference and measure its length.
