Question

Find the difference between the distance covered by the minute hand(3.5cm) and hour hand (2.1cm) of a clock in one rotation

Answer 1

Answer:

8.8 cm

Step-by-step explanation:

distance covered by the minute hand in one rotation= 2$\pi$r

= 2 x $\frac{22}{7}$ x 3.5

= 22 cm

distance covered by the hour hand in one rotation= 2$\pi$r

= 2 x $\frac{22}{7}$ x 2.1

= 13.2 cm

difference between distance covered by minute hand and hour hand

= 22 - 13.2

= 8.8 cm
