    PHYSICS...please help!!

    Four astronauts are in a spherical space station.

    1) If, as is typical, each of them breathes about 500cm^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year?

    2) What would the diameter (in meters) of the space station have to be to contain all this air?
