' . 7', The Deepwater Horizon oil spill in the Gulf oFMexico on April 20, 2010 was "an environmental disaster of unprecedented proportions" and Was a 'devasming blow to the resourcedependent economy of the region" [1]. According to the Washington Post. it is estimated that 9857 -' _. cubic meters of oil per day spilled into the Gulf of Mexico on August 2, 2010 [2]. ' Assume that an average at 9857 ins/day ofoil spilled into the Gulf of Mexico every day and that it formed a hemispherical dome of radius r on the ocean floor. 1| :1. Find a formula for the volume of oil spilled, in cubic meters, t days after the start of the oil spill. Include units in your answer. I . iv, .- 1). Find the derivative ofyour' volume formula with respect to time. Include units in your answer. , dV' _ - . . c. When the volume of the oil spill is 50, 000 m3. what is the radius of the hemisphere of oil? include units in your answer. Give your answer accurate to 3 decimal places. .- r...) d. Find the rate of change of the radius with respect to time when the volume of the oil spill is 50, 000 m3. Include units in your answer. d ' . l ' e. Since only the oil that is in contact with seawater can mix with seawater, it is important to know how much of the surface area of the oil spill is in contact with seawater. Find the rate of Change of the hemisphere-'5 surface area with respect to time when the volume of the oil spill is 50,000 111'. include units in your answer. You should assume that only the top of the hemispherical dome of oil comes in contact .t with seawater (not the at bottom, which is incontact with the ocean floor)
