the Volume of a sphere is given by [tex]V(r) = \frac{4}{3}\pi(r)^3[/tex](adsbygoogle = window.adsbygoogle || []).push({});

Find the average rate of change of volume with respect to radius as the radius changes from 10 cm to 15 cm.

Ok what I tried is: [tex]\lim_{r\rightarrow 15} \frac{V(r)-V(a)}{r-a}[/tex]

[tex]P(a,V(a))=(15,14 137)\\ Let\ r=10 \lim_{r\rightarrow 15} \frac{\frac{4}{3}\pi(10)^3-14,137}{10-15} = 1989[/tex]

and I would do that for 10 to 15 and get the average rate but somethign is wrong here....
