The radius r of a sphere is increasing at a constant rate of 0.04 centimeters per second. (Note: The volume of a sphere with rad

-Dominant- [34]

Answer:

The rate of the volume increase will be $\frac{dV}{dt}=50.27 cm^{3}/s$

Step-by-step explanation:

Let's take the derivative with respect to time on each side of the volume equation.

$\frac{dV}{dt}=4\pi R^{2}\frac{dR}{dt}$

Now, we just need to put all the values on the rate equation.

We know that:

dR/dt is 0.04 cm/s

And we need to know what is dV/dt when R = 10 cm.

Therefore using the equation of the volume rate:

$\frac{dV}{dt}=4\pi 10^{2}0.04$

$\frac{dV}{dt}=50.27 cm^{3}/s$

I hope it helps you!
