Question

The wheels on Kevin’s bike have a diameter of about 3 feet. How far does the bike travel in 12 complete rotations? (Use 3.14 to represent pi)

Answer 1

Use circumference formula to find one rotation:

C = 2πr = πd

C = 3.14*3= 9.42 feet

Full travel of 12 rotations:

12*9.42 = 113.04 feet Ans.

Answer 2

• 113.04 feet

Explanation:

Use circumference formula to find one rotation:

• C = 2πr = πd
• C = 3.14*3= 9.42 feet

Full travel of 12 rotations:

• 12*9.42 = 113.04 feet
