The volume of a right circular cylinder is V=πr^2h. Find the rate of change of volume with respect to time if r increases at 0.2m/s and h decreases at 0.2m/s. For which values of (r, h) does V increase?

Omg that is a big question and weird words and i’m only 5

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
