The volume V of a right circular cylinder is given by V = r h, where r is the radius and h is the height. If h is held fixed at h = 6 inches, find the rate of change of V with respect to r when r = 2 inches. The rate is in. (Type an exact answer in terms of x.) For the circuit shown to the right, after the switch is closed, the transient current i (in A) is given by i = 1.5(1+0.4t). Find the first three nonzero terms of the Maclaurin expansion of this function. ww 10 60 V ww 10 4.0 F
