Answer 1

The area swept by the minute hand in 5 mint is 51.33 cm²

Explanation :

Length of the minute hand = radius of the clock = 14 cm

=> Area swept in one circle = πr² = 22/7 x 14 x 14 = 616 cm²

since the minute hand complete one circle rotation in 1 hour = 60 minute

=> Area swept in 60 minute = 616

=> Area swept in 5 minute = 616 x 5/60 = 51.33 cm²

Hence the area swept by the minute hand in 5 mint is 51.33 cm²
