Answer 1

Given the total number of revolutions in 2 minutes = 200.

Number of revolutions in 1 minute = 100

Then the total number of revolutions in 1 second = 100/60

                                                                                   = 5/3.


Number of revolutions in 24 seconds = 5/3 * 24

                                                                = 40.


Now,

We know that Angle made in 1 revolutions = 360

Angle made in 40 revolutions = 40 * 360 * pi/180

                                                   $= 40 * 2 * \pi$

                                                   $= 80 \pi$



Hope this helps!
