.
The radius of a cylinder and a highlight%28cross%28semicircle%29%29 hemi-sphere is equal.
If their volumes are equal, which of the two has more height and of what percentage % ?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

V%5Bcyl%5D = pi%2Ar%5E2%2Ah.


V%5Bhemisphere%5D = %284%2F6%29%2Api%2Ar%5E3 = 2%2F3%29%2Api%2Ar%5E3.


They are equal:

pi%2Ar%5E2%2Ah = %282%2F3%29%2Api%2Ar%5E3  --->

h = %282%2F3%29r.
