A) 25
B) 75
C) 50
D) 125
Correct Answer: D
Solution :
Let number of balls = n \[\therefore \] Volume of n balls = Volume of cone \[\Rightarrow \] \[n\times \frac{4}{3}\pi {{r}^{3}}=\frac{1}{3}\pi {{R}^{2}}h\] \[\Rightarrow \] \[n\frac{4}{3}{{(2)}^{3}}=\frac{1}{3}{{(20)}^{2}}\times 10\] \[\Rightarrow \] \[n=125\]You need to login to perform this action.
