A) 25 cm
B) 30 cm
C) 35 cm
D) 40 cm
Correct Answer: B
Solution :
1 \[{{m}^{3}}\]space can contain 1000 litres. \[\Rightarrow \] 1 litre is contained in 1000 cm3 Capacity of the vessel \[=\text{ }500\times 1000\text{ }c{{m}^{3}}\] If r cm be the radius of the cone, we have \[\frac{1}{3}\pi {{r}^{2}}.150=500\times 1000\] \[\Rightarrow \,\,\,\,\,r=\frac{100}{\sqrt{\pi }}\].This helps to find the height.You need to login to perform this action.
