Number of sharks = 4
Number of dolphins = 5
Number of animals = number of sharks + number of dolphins
Number of animals = 4 + 5 = 9
Therefore, the ratio of dolphins to animals = 5:9

Answer:
V = 339.12
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 6
h = 9
Work:
V = πr²(h/3)
V = 3.14(6²)(9/3)
V = 3.14(36)(3)
V = 113.04(3)
V = 339.12
<u>Answer</u>
6
<u>Explanation</u>
let n be the first even number in the sequence.
The 2nd term = n + 2
3rd term = n + 2 + 2
= n + 4
4th term = n + 4 + 2
= n + 6
The sum of these number = 36.
∴ n + (n +2) + (n + 4) + (n + 6) = 36
4n + 12 = 36
4n = 36 - 12
4n = 24
n = 24/4
= 6
The first term is 6.
