A) \[55\pi \]
B) \[110\pi \]
C) \[150\pi \]
D) None of the above
Correct Answer: B
Solution :
Total surface area of the cylinder \[=\pi \,\,2h(R+r)+2\pi ({{R}^{2}}-{{r}^{2}})\] \[=2\pi \times 10\,(3+2)+2\pi ({{3}^{2}}-{{2}^{2}})\] \[=100\pi +10\pi =\,c{{m}^{2}}\]You need to login to perform this action.
