Since the end (base) of a cylinder is a circle, the area of that circle is given by the formula: area of the base
Multiplying by the height we get volume
where:
is Pi, approximately
is the radius of the circular end of the cylinder
height of the cylinder
The radius r of a cylinder is the radius of a base. If you are given the diameter instead, remember to halve it.
you are given:
a diameter of , which means that radius is
and a height of
Part A:






the number of cubic feet of grain that can fit into this silo is
Part B:
Explain how you determined your answer.
the number of cubic feet of grain equals to volume of the silo
