pentagon
pi*r^3
correct, though I was looking for what SHAPE you get for #2. I will edit to reword it.

2) 2/3*pir^3 + 1/3pi *r^3 = pi*r^3
that is the correct volume, but what is the shape?
I know the answers, just want to share some interesting geometry facts, and questions are fun!
1) Which regular polygon contains (hidden within it) the golden ratio?
2) What SHAPE do you get when you add the volume of a hemisphere to that of a cone? (if all three shapes have same height and radius).
