Why does the Orthorhombic crystal system have 3 different crystal types?

Why does the Orthorhombic crystal system have 3 different crystal types?
The Orthorhombic crystals have 3 axes at unequal lengths and faces at 90 deg angles. Why does this result in 3 different crystal types [dipyamid,prism, scalenohedron]? I think there should only be a single Orthorhombic crystal type as there is only the one, same set of axes? Obviously this is incorrect and I cannot see how the 3 axes at unequal lengths set produce three different crystals- all Orthorhombic. Any help is greatly appreciated.
Thank you

What is the area enclosed by the two lines tangent to two tangent circles of different diameter?

Suppose one circle has a radius of 2, and the other's is 3. They touch at one point. Two lines, both touching each circle at one point, enclose an area that I'm not sure how to find. Picture leaning boards against the sides of a snowman. The solution may just require basic geometry, or this may be calculus stuff. If it's the former, just color me stupid, because I can't see it.
