V=hpir^2
900=V
r=3
900=hpi3^2
900=hpi9
divide both sides by 9
100=hpi
divide both sides by pi
100/pi=h
aprox pi=3.141592
31.83=h
height=31.83cm
What kind of triangle is that? Based on the angle measurements, it is equilateral, which means all sides are equal.
You would have to find it in terms of single units:
