Answer:
Relation between V and c is represented as:

When c is halved, V becomes
of its initial value.
Step-by-step explanation:
Height of cylinder = Radius of cylinder = c
Volume of cylinder = V
As per formula:

Where
is the radius of cylinder and
is the height of cylinder
Putting 

The values of c is halved:
Using equation (1), New volume:

By equation (1), putting 

So, when c is halved, V becomes
of its initial value.
