A) \[8470{{m}^{2}}\]
B) \[100m\times 75m\times 22m\]
C) \[50{{m}^{3}}\]
D) \[3{{x}^{2}}h\]
Correct Answer: B
Solution :
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\[=\frac{1}{2}({{b}_{1}}+{{b}_{2}})h\] \[=\pi {{r}^{2}}\]
