Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐

✔ Given, it moves 20 revolutions in 1 hour.

✔ Also, 1 hour = 60 minutes.

✔ So, in 1 minute, it makes (20/60) revolutions

✔ In 25 minutes, it will make {(20/60)×25} revolutions = 50/6 revolutions.

✔ Now, one revolution means 2π radian.

✔ So, 50/6 revolutions mean {(50/6)×2π} radians.
= 50π/3 radians.


✔ Hence, the radians it runs through 25 minutes is 50π/3.
