Final Tip. While it is important to know what you can afford in terms of monthly car payments, that shouldn't be your only measurement of a good car loan. Take a look at all the numbers in the sales contract so that you are fully aware of what you are paying for the car.
What is the length of a roll of carpet? There isn't a standard length for carpet rolls. They are often shipped as large as 200 sq yards depending on how thing the nap is. Carpet widths are most often 12', but they aâ¦re sometimes 15', 13'6, and 6' wide. 12 people found this useful.
Write these measurements down. Find the area of the entire carpet roll and the area of the hole in the center. For example, if the carpet roll is 22 inches, the radius will be 11 inches. Find the area by multiplying 3.14 11 ^2 = 379 .94. If the center hole diameter is 6 inches, the radius will be 3 inches. Find the area by multiplying 3.14 3 ^2 = 28.26. Subtract the area of the center hole from the area of the entire roll to find the adjusted area of the carpet. Using the same example, 379.94 - 28.26 = 351.68. Divide the adjusted area by the thickness of the carpet to find the linear length.
