A bike tire has a radius of 9 inches. How far will the bike travel in 3 revolutions?
(use 3 for pi)

The bike will travel 162 inches.

Step-by-step explanation:

1 revolution = 2(pi)(r) = 2(3)(9) = 54

3 revolutions = 54x3 = 162 inches

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
