A) \[2:1\]
B) \[1:2\]
C) \[4:3\]
D) \[3:4\]

Solution :
Radius of sphere \[=r\] units \[\therefore \]\[\frac{\text{Surface}\,\,\text{area}\,\,\text{of}\,\,\text{sphere}}{\text{Surface}\,\,\text{area}\,\,\text{of}\,\,\text{hemisphere}}\] \[=\frac{4\pi {{r}^{2}}}{3\pi {{r}^{2}}}=\frac{4}{3}\]You need to login to perform this action.
