Step-by-step explanation:

Answer 2

The area of the face of the clock by minute hand between 9 am and 9:35am is 89.80 cm².

The total angle covered by minute hand in 60 minutes = 360°

Now the angle covered by minute hand in 1 minute = 360/60 = 6°.

The minute hand of the clock is 7 cm.

We have to find the area covered by the minute hand from 9 to 9:35 that is in 35 minutes.

Total angle covered in 35 minutes = 6×35 = 210°.

Now area of the sector is given by × πr²

Area of the sector = × πr²

Area of the sector = × π×7² = 89.80 cm².
