Yes it is a rational number
Answer:
Step-by-step explanation:
Like prisms, the volume is found by multiplying the area of one end of the cylinder (base) by its height.
Since the end (base) of a cylinder is a circle, the area of that circle is given by the formula:
area =πr^2
Multiplying by the height h we get
volume =πr^2h
where:
π is Pi, approximately 3.142
r is the radius of the circular end of the cylinder
h height of the cylinder
