The radius of a cone is increasing at a constant rate of 7 meters per minute, and the volume is decreasing at a rate of 236 cubic meters per minute. At the instant when the radius of the cone is 99 meters and the volume is 180 cubic meters, what is the rate of change of the height? The volume of a cone can be found with the equation V=\frac{1}{3}\pi r^2 h. V= 3 1 πr 2 h. Round your answer to three decimal places.

The rate of change of the height is 0.021 meters per minute

Step-by-step explanation:

From the formula

Differentiate the equation with respect to time t, such that

To differentiate the product,

Let r² = u, so that

Then, using product rule

Since

Then,

Using the Chain's rule

∴

Then,

Now,

From the question

At the instant when

and

We will determine the value of h, using

Now, Putting the parameters into the equation

Hence, the rate of change of the height is 0.021 meters per minute.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
