Question

Find the volume of a solid that results when the area of the region enclosed by x+y=4, y=0, x=0 is revolved about the y axis

Answer 1

i think this is calculus II question, the volume of area under x or y rotation. i think!! you have to first solve the equation to get the dx/dy since its rotating under y axis. once you get that you solve the equation with a table of values, with the use of a math table, then once you add the values you will get the estimate ;-) i thnk av confused you more! bt thats my blurred memory working!
