Answer:
The rate of the volume increase will be 
Step-by-step explanation:
Let's take the derivative with respect to time on each side of the volume equation.

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:

Sq root of 64 =8 so sq root of 65 must be just a little larger than 8

If I'm correct that's the answer
Looks like choice B would be the best description of an output.. Usually, output refers to the dependent value of a function rule. It is also correct that the y coordinate of ordered pairs, graphed points, and in a function table.
