Find the area of the region that is inside r=3cos(theta) and outside r=2-cos(theta). sketch the curves.

The volume of a spherical hot air balloon v(r) = 4 3 ? r3 changes as its radius changes. the radius is a function of time given by r(t) = 3t. find the instantaneous rate of change of the volume with respect to t at t = 2.
