    Use the formula for the volume of a sphere: \[V=\frac{ 4 }{ 3 }\pi r^3\]Because it's a hemisphere, you know what to do next...

    Well, r = 15. Put it in the formula...

    This will give you the volume of a sphere with a radius of 15. (use calculator). Now think what you have to do to calculate the volume of a hemisphere with the same radius ;)
