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)

In 1 hour, minute hand completes one round means makes a circle.
Radius of the circle (r) = 15 cm
Circumference of circular clock = 2πr
= 2 x 3.14 x 15
= 94.2 cm
Therefore, the tip of the minute hand moves 94.2 cm in 1 hour.
