Answer:
30.29 s
Explanation:
We are given that
Radius=r=6 cm
Length of an arc=l=19 cm
We have to find the value of t in seconds.
Substitute the values then we get
We know that
1 minute=60 seconds
In 60 seconds ,second hand makes an angle=
radian
radian made by second had in 60 sec.
1 radian made by second hand in 
sec
3.17 rad made by second hand in 
Hence, the value of t =30.29 s
