A) 20cm
B) 15cm
C) 10cm
D) 18cm
Correct Answer: B
Solution :
Volume of cuboid = Volume of cylinder \[\Rightarrow \]\[lbh=\pi {{r}^{2}}h\] \[\Rightarrow \]\[{{r}^{2}}=\frac{44\times 30\times 15\times 7}{22\times 28}\] \[\therefore \] \[\text{r}=\text{15 cm}\] Hence radius of the cylinder is equal to 15 cm.You need to login to perform this action.
