A) \[13\,L\]
B) \[27\text{ }L\]
C) \[42.94\text{ }L\]
D) \[28.49\text{ }L\]
Correct Answer: D
Solution :
Volume of bucket \[=\frac{\pi h}{3}[r_{1}^{2}+{{r}_{2}}^{2}+{{r}_{1}}{{r}_{2}}]\] \[=\pi \times \frac{15}{3}[{{(28)}^{2}}+{{(21)}^{2}}+28+21]\] \[=28490\,c{{m}^{3}}\] \[\therefore \] Volume of bucket \[=28490\text{ }c{{m}^{3}}=28.49\]You need to login to perform this action.
