In Making 1000 Revolutions, a Wheel Covers 88 Km. the Diameter of the Wheel is - Mathematics

MCQ
Sum

In making 1000 revolutions, a wheel covers 88 km. The diameter of the wheel is

• 14 m

• 24 m

•  28 m

• 40 m

Solution

28 m
Distance covered by the wheel in 1 revolution=((88xx1000)/1000) "m'

= 88 m

We have:

Circumference of the wheel = 88 m

Now, let the diameter of the wheel be d m.

Thus, we have:

πd = 88

=>22/7xx"d"=88

=> "d" =(88xx7/22)

⇒ d = 28 m

Is there an error in this question or solution?
