Please Help!

Marion has a bicycle that she is planning to take for a ride. The rim of the rear wheel lies 37 cm from the center of the wheel. The tire itself has a thickness of 4 cm.
In order to Marion to ride her bicycle 95,267.6000000000 cm, approximately how many rotations will the rear wheel make?
A. 314.5
B. 18
C. 414.4
D. 370

Answer 1

To solve the question we need to calculate the total circumference of the wheel plus the rim.
Total diameter will be:
d=(4+4+37+37)=82 cm
hence:
C=πd
C=3.14×82
C=257.48 cm
Thus the total rotations required to cover 95267.6 cm will be:
Rotations=95267.6/257.48
=370 rotations

Answer: D] 370 rotations
