Question

a wheel covers a distance of 9.5km in 2000 revolutions . If the diameter og wheel is N/10(in meter) then find value of N

Answer 1

Answer:

The value of N = 15.11 m

Explanation:

distance covered = 9.5 km = 9500 m

Number of revolutions   = 2000

diameter of wheel d = N/10  m = 2000

no of revolutions x circumference of wheel  = distance covered

2000 x π d = 9500

2000 x $\frac{22}{7}$ x $\frac{N}{10}$ = 9500

N = $\frac{ 7 X 10 X 9500}{2000 X 22}$ = 665/44 = 15.11 m
