Chapter 12.7, Problem 36E

Changes in cone volume The volume of a right circular cone with radius r and height h is $V=\pi r^{2}h/3$.

a.    Approximate the change in the volume of the cone when the radius changes from r = 6.5 to r = 6.6 and the height changes from h = 4.20 to h = 4.15.

b.    Approximate the change in the volume of the cone when the radius changes from r = 5.40 to r = 5 37 and the height changes from h = 12.0 to h = 11.96.
