Can someone help me with this question?

987 cubic foot

Step-by-step explanation:

we need to find the volume of each of them.

container A = πr²h

=22/7*(10)² * 10

=22/7 * 100 *10

= 22000/7 cubic feet

container B

=πr²h

=22/7 *7*7*14

= 22*7*14

= 2156 cubic foot

22000/7 - 2156    (to find empty space volume)

= 22000- 15092/7

= 6908/7

=986.85... ≈ 987 cubic foot.
