Answer:
660.4
Step-by-step explanation:
If the bike wheel is 26 inches in diameter, and 1 inch = 25.4 millimeters then we simply need to convert inches to millimeters, which can be done by multiplying the number of inches by 25.4. The reason we chose 25.4 is that 1 inch = 25.4 millimeters.
26 x 25.4 = 660.4
