(1) The region bounded by the given curves is rotated about y = 9. x=(y-10)^2 , x=1. Find the volume V of the resulting solid by any method. and (2) The region bounded by the given curves is rotated about the y-axis. y=-x^2+15x-54, y=0. Find the volume V of the resulting solid by any method. I got (...
I am studying for an exam and I don't you know how to go about this? Volume of solid under the curve y= 7/(x^2 +5x +6) from x = 0 to x = 1 if rotated about the y-axis. I made x the subject of the formula getting (sqrt(y+28)-5 sqrt(y))/(2 sqrt(y)) and then I found what y is when x= 0 and x=1, which w...
