They're similar in that you take 1/3 of the volume of a different figure.

For a cone, you take 1/3 of the volume of a cylinder.
For a pyramid, you take 1/3 of the volume of a rectangular prism.

The two are different in that the cone has a circular base while the pyramid has a polygonal base (example: a pyramid of Egypt has a rectangular base)

A is Area of the base.
Like:
volume of a cone: V=%281%2F3%29%2AA%2Ah
volume of a pyramid: V=%281%2F3%29%2AA%2Ah
same formula
Different:
volume of a cone: A is circle (A=p%2Ar%5E2%29)
volume of a pyramid: A is square (A=s%5E2%29)
