A) \[50\,\pi c{{m}^{3}}\]
B) \[100\,\pi c{{m}^{3}}\]
C) \[125\,\pi c{{m}^{3}}\]
D) \[150\,\pi c{{m}^{3}}\]
Correct Answer: B
Solution :
[b] The resulting solid is a right cone with radius 5 cm and height 12 cm. Volume \[=\text{ }\frac{1}{3}\,\,\,\pi {{5}^{2}}.12\,\,\,c{{m}^{3}}=100\text{ }\pi c{{m}^{3}}.\]
