A) 37.5 m
B) 150 m
C) 75 m
D) None of these
Correct Answer: D
Solution :
(d): Area of base \[=6\times 10=60\,\,{{m}^{2}}\] Volume of tent \[=30\times 10=300\,\,{{m}^{3}}\] Let the radius be = r, height = h, slant height = l \[\therefore \] \[\pi {{r}^{2}}=60\Rightarrow r=\sqrt{\frac{60}{\pi }}\] Also, \[300=\frac{\pi {{r}^{2}}h}{3}\] \[\Rightarrow \] \[900=\pi .\frac{60}{\pi }.h\] \[\Rightarrow \]\[h=15\,\,m\]You need to login to perform this action.
