Acylinder is being flattened so that its volume does not change. find the rate of change of radius when r = 2 inches and h = 5 inches, if the height is decreasing at 0.7 in/sec. hint: what is the rate of change of volume?

Explanation:

As the volume of the cylinder is constant here so we can say that its rate of change in volume must be zero

so here we can say

now we have

now find its rate of change in volume with respect to time

now we know that

given that

h = 5 inch

r = 2 inch

now we have

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close
