I just measured an unused roll. You're not going to believe this............18 inches!

I don't know that there is a 'standard' roll of duct tape. The amount you get is usually measured by its length. A good size roll is usually about 8" in diameter, so its circumference would be 2*pi*r = 2 * 3.14159 * 4 = about 25 inches....

This number would change with the supplier of the duct tape, and with the amount you have used. The circumfrence of a circle is 2 times the radius times pi, or the diameter times pi (pi equals 3.14).

It relys heavily on what size duct tape you have. To calculate this, I do not recommend following the other bone heads math equation. the formula is C=pi*D
C is for circumference
pi is appx. 3.14159
and D is the actual diameter of the roll of tape.
the other formula is an incorrect way of finding the area of a circle

What Duct Tape Company are you talking about ? I'm sure there are different standards for different companies.
