A) \[56c{{m}^{2}}\text{ and }560c{{m}^{2}}\]
B) \[560c{{m}^{2}}\text{ and }56c{{m}^{2}}\]
C) \[56c{{m}^{2}}\text{ and 61}6c{{m}^{2}}\]
D) \[{{r}^{2}}\]
Correct Answer: A
Solution :
Radius of the largest cone, \[\Delta AOB\]edge of the cube \[Arc\frac{\theta }{{{360}^{o}}}\times 2\pi r,\] Also, height of the cone h = edge of the cube = 9 cm Hence, the required volume \[\theta \] \[(\pi =3.14)\]You need to login to perform this action.
