The minute hand of a watch is 3 cm long. How far does its tip move in 25 minutes? [use `pi=3.14`]

Explanation

To find the distance traveled by the tip of the minute hand in 25 minutes, we can follow these steps:

### Step 1: Understand the problem
The minute hand of a watch moves in a circular path. The length of the minute hand is given as 3 cm, which is the radius (r) of the circle.

### Step 2: Calculate the circumference of the circle
The circumference (C) of a circle can be calculated using the formula:
\[ C = 2\pi r \]
