A) 3 cm
B) 4 cm
C) \[\frac{4}{3}\]cm
D) 5 cm
Correct Answer: D
Solution :
Let radius of cylinder be 5x and height be 7x. \[\therefore \] Volume \[=\pi {{r}^{2}}h=550\] \[\frac{22}{7}\times {{(5x)}^{2}}\times 7x=550\] (Given) \[22\times 25{{x}^{3}}=550\] \[{{x}^{3}}=\frac{550}{22\times 25}=1x=1\] Here, radius \[=5x=5\times 1=5\,\,\text{cm}\]You need to login to perform this action.
