Q.17 The minute hand of a circular clock is 15 cm long. How far does the tip of the minute hand move in 1 hour? (Take $$\pi$$ = 3.14)

Length of minute hand = 15 cm
$$\therefore$$Radius = 15 cm
Circumference = 2$$\pi$$ r = 2 × 3.14 × 15 cm = 94.2 cm
Since the minute hand covers the distance in 1 hour equal to the circumference of the circle. Here the required distance covered by the minute hand = 94.2 cm.
