The minute hand of a clock is `sqrt(21)` cm long. Find the area described by the minute hand on the face of the clock between 6 a.m. and 6.05 a.m.

Explanation

To find the area described by the minute hand of a clock between 6 a.m. and 6:05 a.m., we can follow these steps:

### Step 1: Determine the length of the minute hand
The length of the minute hand is given as \( \sqrt{21} \) cm.

### Step 2: Calculate the angle covered by the minute hand in 5 minutes
In 60 minutes, the minute hand covers a full circle, which is 360 degrees. Therefore, in 1 minute, the angle covered is:
\[
