A) \[343.72\text{ }c{{m}^{3}}\]
B) \[266.11\text{ }c{{m}^{3}}\]
C) \[532.22\text{ }c{{m}^{3}}\]
D) \[133.55\text{ }c{{m}^{3}}\]
Correct Answer: B
Solution :
(b): Height of cone \[=10.2-4.2=6\,\,cm\] Volume of wood \[=\frac{\pi {{r}^{2}}h}{3}+\frac{4\pi {{r}^{3}}}{3\times 2}\] \[\Rightarrow \] \[\frac{3.14\times {{(4.2)}^{2}}\times 6}{3}+\frac{4\times 3.14\times {{(4.2)}^{3}}}{3\times 2}\] \[\Rightarrow \] \[266.11\,\,c{{m}^{3}}\]You need to login to perform this action.
