PRE-CALC still stuck

Write the statement as a power function equation. Use k for constant of variation if one is not given.
a. Charles's law states the volume V of an enclosed ideal gas at a constant pressure varies directly as the absolute temperature T.
b. The volume V of a circular cylinder with a fixed height is proportional to the square of its radius.
c. the current I in an electrical circuit is inversely proportional to the resistance R, with constant of variation V.
I can't figure out how to do this. I was looking at my old notes but can't seem to come up with something.
