Oil spilled from a ruptured tanker is spreading in a circular pattern. If the radius of the circle is
increasing at the constant rate of 1.5 feet per second, how fast is the area of the spill increasing when
the radius of the spill is 42 feet?

Best ResponseYou've already chosen the best response.1you are told \(r'=1.5\) and \(r=42\) plug in the numbers and get \(A'\) in one step

Best ResponseYou've already chosen the best response.1well only the formulas get harder to figure out, i am willing to bet that you knew the formula for the area of a circle
