Question

A wheel completes 2000 revolutions to cover the 9.5 km. distance. then the diameter of the wheel is

Answer 1

Ans is 1.5m Using this formula n2(pi)r and substituing the values we get 1.5m

Answer 2

Answer:

1.5119 meters.

Step-by-step explanation:

Let d be the diameter of the wheel.

Circumference of wheel = πd

In one revolution, the wheel covers a distance equal to the circumference of the wheel.

Hence, in 2000 revolution, the wheel covers a distance of 2000πd

Now, it should be equal to 9.5 km

Therefore, we have

2000πd = 9.5

d = 9.5/2000π

d = 0.00151197 km

d = 1.5119 m

The diameter of wheel is 1.5119 meters.
