College Physics (7th Edition)

Pressure depends only on depth, $P=density\times g\times h$. To get the same water pressure, spherical tanks do not need as much water as cylindrical tanks. Also, spherical shapes can distribute pressure more uniformly so that it reduces the risk of tank damage by pressure.
