Question

A wheel covers a distance of 9.5 km in 2000 revolutions. The diameter of the wheel is

Answer 1

Answer:2.457 m

Step-by-step explanation:

Circumference of wheel =πr^2=π(d^2/4)

Now ,

{ πd^2/4}×2000=9.5

Or,πd^2×500=9.5

Or,(22/7)*d^2*500=9.5

Or,d^2=(9.5*7)/(500*22)

Or,d^2=66.5/11000

Or,d^2=0.00604km

Or,d^2=0.00604×1000 m

Or,d^2=6.04m

Therefore d=√(6.04) m =2.457 m
