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.
