I have the following function:

$$ u(r)= \frac{4}{3} \pi r^{3} $$

I need to calculate the % change of volume of the sphere using differential if I increase the radius by 1% (0.01).

Can anyone help me here, I'm clueless how to solve this.

    Given the suggested approach, the obvious first steps are to try and answer the questions "what is the differential?" and "How does the differential measure change?"2012-12-30
