Answer 1

hope you got your answer

Answer 2

Answer:

$\frac{50\pi}{3}$

Step-by-step explanation:

No. of revolutions in 60 minutes = 20

No. of revolutions in 1 minute = $\frac{20}{60}$

No. of revolutions in 25 minutes = $\frac{20}{60} \times 25$

                                                     = $\frac{25}{3}$

1 revolution = $2\pi$ rad

So, $\frac{25}{3}$ revolutions= $\frac{25}{3}\times 2\pi$

                                                           = $\frac{50\pi}{3}$

Thus the radians it runs through 25 minutes is $\frac{50\pi}{3}$.
