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.
 
        
             
        
        
        
Answer:
 km per min
Step-by-step explanation:

Answer:
Step-by-step explanation:
You need to give us the choices. However, I will try and give you the answer.
The highest common factor is 8
8(x^2 - 3)     This is the answer I think the question expects.
8(x - √3 )(x + √3)  this is also possible
