(1 point) during early development, the limb of a fetus increases in size, but has a constant proportion. suppose that the limb is roughly a circular cylinder with radius r and length l in proportion l/r=c where c is a positive constant. it is noted that during the initial phase of growth, the radius increases at an approximately constant rate, i. e. that dr/dt=a. at what rate does the mass of the limb change during this time? [note: assume that the density of the limb is 1 gm/cm3 and recall that the volume of a cylinder is v=al where a is the base area (in this case of a circle) and l is length.]dm/dt=
