Question

The minute hand of a watch is 1.5 cm long. How far does its tip move in 40 minutes?(use π=3.14)

Answer 1

Answer:

Total circumference of the clock=2πr=2 × 3.14 × 1.5

                                                                =9.42 cm

distance covered in 60 minutes = 9.42 cm

dictance covered in 1 minute= 9.42/60

therefore, distance covered in 40 minutes= 9.42/60 × 40

                                                                         =6.28 cm

hope it helps you !
