Answer:
Domain =

Range =

Explanation:
Domain: The set of all possible value of independent variable(x) where function is defined.
Range: The complete set of all possible resulting values of the dependent variable(y).
As per the statement:
The formula for the volume of a cylinder with a height of 5 units is:

where, r is the radius of the cylinder and r cannot be in negative i.e

here, r is the independent variable and V(r) is the dependent variable
by definition of domain and Range
Domain of the given function is:
or in interval =

Range of the function(V(r)) is:
