A) 3
B) 4
C) 6
D) 7
Correct Answer: C
Solution :
If r be common radius of the base, h be the height of cylinder, I be the slant height of the cone, then curved surface of the cylinder \[=2\pi \,r\,h\]curved surface of the cone \[=\pi \,r\,l\] Since \[\pi \,r\,l=2\pi \,rh\] therefore \[l=2\,h=6m\]You need to login to perform this action.
