Answered by khushishrivastav2002

Answer:

Explanation:Radius is given 10.5cm

Therefore, circumference=2πr

=66cm

Speed of the tip of second hand=circumference of dial of the clock/time taken by the second hand to complete one round

=66cm/60s = 1.1cm/s

Answered by deeplikaraydiya

Explanation:

Given:

radius=10.5cm

circumference=2*22/7*10.5

=>44*1.5

=>66cm

time taken for 1round =60s

Therefore , speed =distance/time

=66/60

=1.1cm/s
