\[\sec^2 x  2 = \tan^2 x \]\[\sec^2 x  1 = \tan^2 x +1\]\[\sec^2x=\tan^2x+1\]\[\sec^2x1=\sec^2x\]\[1 \not= 0\]No Solution

A highaltitude spherical weather balloon expands as it rises due to the drop in atmospheric pressure. Suppose that the radius r increases at the rate of 0.16 inches per second and that r = 38 inches at time t = 0. Determine the equation that models the volume V of the balloon at time t and find the volume when t = 280 seconds.
