Let's do this question how much distance in meters a will of twenty five centimeters radius will cover
if it rotates 350 times.
All right, pause the video, give it a try and then let's do it together.
All right.
We're back over here.
We have a visual right now.
If this will repeat one time, how much distance would you travel?
It will travel the distance equal to its circumference.
Right.
Imagine it's on a straight surface.
Now, the wheel is over here, right.
And at this point is touching the wheel at the surface.
Now, if you rotate, this will ride.
If you rotated, it will move forward.
But even after some time, it will be somewhere over here.
Right.
And if you keep doing that till it's back over here.
Right.
What would be this distance, this distance that has been traveled will be equal to the circumference
of the circle?
All right, now the circumference is equal to two Pyaar, and it's given that the radius is twenty five
centimeters.
Right.
So that's equal to two in the 22 by 17 to twenty five.
That's the distance that will be traveled when it rotates one time.
Now it's given that it rotates 350 times.
So if you drop its one time, it's this much.
So if it's rotating three 50 times, the distance covered will be 350 in the amount traveled when it
rotates one time.
That's 350 in the two in the 22 by seven and the twenty five that's equal to fifteen to forty four and
twenty five.
And that gives you the answers by five 00 centimeter.
Or that's the same as by one hundred and fifty meter.
And that's the answer to this question.
