A) 8
B) 12
C) 14
D) 16
Correct Answer: B
Solution :
Radius = 4x cm and slant height\[(l)=7x\,\,\text{cm}\] \[\therefore \]\[\pi rl=\frac{22}{7}\times 4x\times 7x=792\] \[\Rightarrow \]\[{{x}^{2}}=\frac{792\times 7}{22\times 4\times 7}=9\] \[\therefore \]\[x=3\] Radius \[=4\times 3=12\,\,\text{cm}\]You need to login to perform this action.
