Since a sphere's surface area is 4πr², we then need to find r as a function of time t, which is 9t (since it increases by 9 every second)+0 (the initial value)=9t. Plugging it in, we get 4π(9t)²=4π*36t²=144πt²
Answer:

Step-by-step explanation:
24y = 7
Our primary objective here is to get y on it's own side, without any numbers attached.
Since a 24 is attached to the y, we have to divide the 24y by 24.


Remember that whatever we do to one side, we MUST do to the other.

Since
can't be simplified, that would be our answer.
