An oil spill off the California coast spread in a circular patch. The radius of the spill increased at a rate of 38 meters/hr and will greatly affect the local wildlife, particularly if the area increases at a rate of 20000 m/hr or more. This makes the spill very difficult to contain. How fast is the area of the patch increasing when the patch has a radius of 100 m? Would this create a problem for the clean-up efforts of the U.S. Coast Guard?
