Question

Jim has 20-inch wheels on his bicycle (their diameter is 20 inches). The tires are worn out, and he would like to cut them into pieces to use as a bumper on something he's making. Estimate the length of rubber Jim would get from his two bicycle tires.

A. 60 inch
B. 40 inch
C. 120 inch
D. 136 inch

Answer 1

You need to find the perimeter of it
The formula for that is c=2PIr
2*3.14*10 = 62.8
But there's two wheels so 62.8*2 = 225.6 .. it could be c or d

Answer 2

The answer would most likely be 40 inches
