Answer:
Part a)
Part b) (see the explanation)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
where
B is the area of the base of cylinder
h is the height of the cylinder
we have that
Part a) Write the function, V(h), that represents the volume of the cylinder
we have
----> the radius is half the diameter
substitute
The volume is
Part b) Find V(3) and tell what it represents
V(3) represent the volume of the cylinder with a height of 3 inches
so
For h=3 in
substitute
