A) 100%
B) 2000%
C) 300%
D) 400%
Correct Answer: A
Solution :
Let r and h be the radius and height of the cone. \[\therefore \] Original volume \[=\frac{1}{3}\pi {{r}^{2}}h=V\] New radius = r and new height = 2 h New volume \[=\frac{1}{3}\pi {{r}^{2}}\times 2\,h=2\,V\] \[\therefore \] Increase in volume \[=2V-V=V\] Increase percentage of volume \[=\left( \frac{V}{V}\times 100 \right)%=100%\]You need to login to perform this action.
