Answer:
23 units
Step-by-step explanation:
Since both lines are chords, they're equal in length. This means we can set them equal to each other.
2x + 2x +2 = 15 + 8
This becomes 4x + 2 = 23.
Subtract two from each side to get 4x = 21.
Now divide by 4 to isolate x.
This makes x = 5.25.
Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units

Answer:
1017.4 m³
Step-by-step explanation:
Volume of cone V = (1/3)πr²h
pi = 3.14
r = 9 and r² = 81 m²
h = 12 m
V = (1/3)*3.14*81*12
V = 1017.36 rounded 1017.4 m³, which is the first answer.
