Kevin is 6-7 years old as 6.2222222222 x 9 is 56
Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.
<h3>What is the volume of a sphere?</h3>
The volume of a sphere of radius r is given by:

Applying implicit differentiation, the rate of change is given by:

In this problem, we have that:

Hence the rate of change of the radius is given as follows:




The radius is increasing at a rate of 0.0081 cm per minute.

Step-by-step explanation:
ANSWER
or 
EXPLANATION
For 
We make y the subject to obtain,

We can easily graph this function, because we just have to transform the graph of
by shifting the intercept up to
.
As for the straight line,
,
We find the intercepts as follows,
When
.
When
.
We plot the points
and
.
We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
