The length of minute hand of a circular clock = 15cm
The clock is the circle
The minute hand is the radius = 15cm
The distance that the tip of the hand covers = circumference of the circle
= 2πr
= 2(22/7)(15)
= (approx) 94.25 cm

In one 1 hour, the tip will complete one rotation
radius = 15 cm
so, distance = circumference = 2πr = 2×π×15
                                                = 
30π cm
                                                = 94.2 cm
