Answer:
The length of metal band around the given clock is 50. 24 cm.
Step-by-step explanation:
Here, the diameter of given clock = 16 cm
Now, Diameter = 2 x Radius
So, Radius = D/2 = 16 cm/2 = 8 cm
⇒The radius of the clock = 8 cm
Now, The metal Band around it = The CIRCUMFERENCE of the watch
Circumference of the clock = 2 π r
= 2 x ( 3.14) x ( 8) = 50.24 cm
or, C = 50.24 cm
Hence, the length of metal band around the given clock is 50. 24 cm.
