Question

In making 1000 revolutions, a wheel covers 88 km. The diameter of the wheel is
A. 14m B. 24m C. 28m D. 40m

Answer 1

Answer:

28metre , hope it is useful for you, please mark as brain list

Answer 2

Answer:

28 m

Step-by-step explanation:

Distance = 88 km = 88000 m

In 1 revolution wheel travels 2πr distance,

Number of revolutions wheel make = 1000 revolutions.

We have to find radius now.

r = 88000/2 * 22/7 * 1000

= 616/44

= 14 m

Thus, radius of wheel = 14 m.

Diameter of the wheel = 14 * 2 = 28 m.

• Hence, Diameter = 28 m.
