Answer:
Step-by-step explanation:
volume V1=4/3 π(r1)³=4/3 π×7³
V2=4/3 π(r2)³=4/3 π×4³
V1-V2=4/3 π(7³-4³)=4/3π(343-64)
=4/3×π×279
=4π×93
=372π mm³

Let's do

Release k for some while
If
So
So vertical asymptote is at origin now
It mentioned that it's at x=-5 so we need to change x


- Vertical asymptote at x=-5
Now
- for k=0 horizontal asymptote at origin
But it's given
Same put y=12 in place of k

Graph attached for verification
Note that x is the hypotenuse of a right triangle. Applying the Pyth. Thm.,
x^2 = 2^2 + 6^2, or x^2 = 4 + 36 = 40.
Thus, the hypotenuse is +sqrt(40), or 2sqrt(10).
