The length of the minute hand of a clock is 14 cm. Find the area swept by the minute hand in 5 minutes.

Given: Radius = 14 cm

To find: Area swept in 5 minutes.

Explanation:

We know,

….. (1)

Angle covered in 60 min = 360°

Angle covered in 1 min = 360° /60° = 6°

Angle covered in 5 min = 5×60°

= 30°

Put the known values in (1) to get,

= 51.30 cm²

Hence area swept by the minutes hand in 5 min is 51.30 cm².
