A business manufactures acrylic cylinders. For a particular model of cylinder, the height is always twice the radius. Create and write a function, V(r) that calculates
the volume of water based on the radius of the cylinder. Write this function in
simplest form. Then create and write a function, M(V) that calculates the mass of
the water based on the volume of the water. (The density of water is approximately
28 grams per cubic meter.) Then write a composite function in simplest form in
which the domain values represent the radius of the cylinder and the range values
represent the mass of the water in the cylinder. Write your response in terms of pi
