Answer:
.
Step-by-step explanation:
We are given that

Volume of sphere=


Integrating on both sides then we get

Substitute r=4 and t=0




Substitute t=5


Hence, the volume is changing at the rate of

➷ Use the geometry rule:
(|(20(-2) - 21(3) - 42|) / square root of 20^2 + (-21)^2
Now you get:
(x + 2)^2 + (y - 3)^2 = 5^2
This can also be written as:
x^2 + 4x + y^2 - 6y - 12.
It would be option B
