A) 11498.67 \[c{{m}^{3}}\]
B) 12298 \[c{{m}^{3}}\]
C) 23598.67 \[c{{m}^{3}}\]
D) 1248.67 \[c{{m}^{3}}\]
Correct Answer: A
Solution :
(a): Surface area \[=2464=4\pi {{r}^{2}}\] \[\Rightarrow {{r}^{2}}=\frac{2464}{4\pi }\] \[\frac{2464\times 7}{4\times 22}\] \[=\frac{308\times 7}{11}=28\times 7\] \[\Rightarrow r=14\,.\] \[\therefore \]vol\[=\frac{4}{3}\times \frac{22}{7}\times 14\times 14\times 14\] \[=\frac{88\times 28\times 14}{3}=\frac{88\times 392}{3}\] = 11498.67.
