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.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

irrational, cannot
