Hubble constant is H in your equation. Pi and G are constants so ignore them and just toss in a couple of simple values for H and you get your answer (H is lower value if the recession rate is slower)
 
...anything about Hubble's Constant? Can someone help me with this?

If Hubble's constant were discovere dto be a slower recession rate than current estimates, would this result in a higher or lower critical density for the universe? Show that your answe is true with the following formula: pcrit=3H^2/8piG

Please help!
