7. The diameter of the front wheel of a bicycle is 16 inches while the diameter of the rear wheel is 20
inches. If the front wheel has made 3000 revolutions
to travel a certain distance, how many revolutions
would the rear wheel have made?
A. 3750
B. 2400
C. 2100
D. 1800
#wrong answer will report

Given :-Diameter of front wheel of cycle = 16 inchesDiameter of rear wheel = 20 inchesRevolution of front wheel = 3000To Find :-Revolution made by rear wheelSolution :-

As we know that

Circumference = 2πr or πd

R is the RadiusD is the Diameterπ × 16 × 3000 = π × 20 × x

Assumed revolution as x

16 × 3000 = 20 × x48,000 = 20x48,000/20 = x2400 = x

Hence :-Total revolution = 2400

Here are the answers to the ones that i could see.
