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 π = 3.14)

Solution:

Radius of the circular clock (r) = 15 cm

Circumference of the circular clock = 2πr

= 2 × 3.14 × 15 cm

= 94.2 cm

Therefore, the tip of the minute hand moves 94.2 cm in 1 hour.
