 Hi and welcome to the session. Let us discuss the following question together. It says, a wheel makes 360 revolutions in one minute. Through how many radians does it turn in one second? Now here in this question we need to find our answer in radians. And a wheel is given to us. A wheel is in a shape of a circle, right? Right. Now at the center one revolution subtends an angle of 2 pi at the center. Right. The knowledge of this formula is the key idea that we are going to use in order to proceed on with our solution. So it is given to us in the question that in one minute, a wheel takes 360 revolutions. Right. So in one minute, in one second, we will take 360 multiplied by 1 by 60 because in one minute there are 60 seconds. So one second consists of 1 by 60 minutes. So that means in one second wheel takes 6, 6 revolutions. Right. Now as we discussed in our key idea, one revolution makes an angle of 2 pi radian at the center. So 6 revolution will make, will make 2 pi multiplied by 6 radians at the center that is equal to 12 pi. So our answer is 12 pi that is 12 pi radians does a wheel makes in one second. This completes the question that was given to us. I hope you enjoyed the session. Bye for now.
