Hello!
The find the volume of a cone you divide the product of the base and height by 3. First we find the area using

r².
A=49(3.14)=153.86
Now we multiply this by the height.
153.86(18)=2769.48
Now we divide by 3.
2769.48/3=923.16
Now we divide this number by 21 to see how many days it will take for the container to become empty.
923.16/21=43.96≈44
Therefore, our answer is
A) 44 days.
I hope this helps!
