A) \[393\]
B) \[429\]
C) \[492\]
D) \[294\]
Correct Answer: B
Solution :
\[V=\pi \,({{R}^{2}}-{{r}^{2}})h\] \[=\frac{22}{7}\,({{8}^{2}}-{{5}^{2}})\,\left( 3\frac{1}{2} \right)\] \[=\frac{22}{7}(64-25)\,\left( \frac{7}{2} \right)\] \[=\frac{22}{7}\times 39\times \frac{7}{2}\] \[=11\times 39=429\]You need to login to perform this action.
