(i) A broken pipe at an oil rig off the east coast of Trinidad produces a circular oil slick that is S
meters thick at a distance x meters from the break. It difficult to measure the thickness of the
slick directly at the source owing to excess turbulence, but for x>0 they know that

If the oil slick is assumed to be continuously distributed, how thick is expected to be at the
source?
