Answer 2

Answer:

Answer is 5000.

Step-by-step explanation:

GIVEN, that the radius r of the wheel is

$= 35cm \\ = 35 \times {10}^{ - 5} km$

∴ It's circumference C =

$2\pi \: r \: when \: \pi = \frac{22}{7}$

$so \: \\ c = 2 \times \frac{22}{7} \times 35 \times {12}^{ - 5}$

$km \: = 220m$

The distance the automobile travels = 11 km

In one revolution the wheel can cover = it's circumference C

So the number of revolution n to

$\frac{d}{c}$

$i.e = \frac{11}{200 \times {10}^{ - 5} } = 5000$

Answer,

The number of revolution the wheel 5000
