At what rate is the volume of the cone changing when the radius is 120 inches and theheight is 144 inches?27445 27445 in3/s6. 3/3 points | Previous AnswersThe voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistanceR is slowly increasing as the resistor heats up. Use Ohm's Law, V = IR, to find how the current I ischanging at the moment when R = 400 , I = 0.08 A, dV/dt = -0.01 V/s, and dR/dt = 0.03 /s.-0.000031 -0.000031
