Question

the diameter of wheel of car is 70cm. how much distnnce wil it cover in 50 revolutions​

Answer 1

Answer:

110m.

Step-by-step explanation:

In one revolution it will cover distance equivalent to its perimeter.

As diameter is 70cm, its radius is 35cm.

So, distance travelled in 1 revolution = 2π(35) = 70π cm.

Distance travelled in 50 revolutions = 50 * 70π = 3500π = 11000 cm = 110m.

( Put value of π = 22/7 )

Thank you.

Answer 2

Answer:

110m

Step-by-step explanation:

$circumfernce \: of \: wheel \: = \pi \times dia \: of \: wheel \\ = \frac{22}{7} \times 0.7 \: metre \\ = 2.2 \: m \\ distance \: travelled \: = \: circumference \: of \: wheel \: \times \: no. \: of \: revolution \\ = 2.2 \times 50 \\ = 110 \: m$
