• # question_answer The surface area of a sphere is x. What is its volume? A)  $8470{{m}^{2}}$              B)  $100m\times 75m\times 22m$ C)  $50{{m}^{3}}$                  D)  $3{{x}^{2}}h$

Let r be the radius of the sphere, then ${{d}_{1}}$ ${{d}_{2}}$ ${{90}^{o}}$ $=\frac{1}{2}\left( sum\text{ }of\text{ }parallel\text{ }sides \right)\times height$ Volume$=\frac{1}{2}({{b}_{1}}+{{b}_{2}})h$ $=\pi {{r}^{2}}$
