I have a homework question that I am having troubles with.(adsbygoogle = window.adsbygoogle || []).push({});

Q: By equating the pressure at the centre of an icy planetesimal to the maximum pressure that cold ice can sustain without deforming, about 40 MPa, find a lower limit to the diameter of an icy minor planet.

The part I dont understand is the "lower limit to the diameter"

Do I use: P_{central}>[itex]\frac{GM^{2}}{8πr^{4}}dm[/itex]

I just dont know how to get the diameter....
