A tank formed by rotating y = 4x 2 , 0 ≤ x ≤ 1 about the y-axis is full of water. The density of the water is given by rho = 62.5 lb/ft3 . Find the work required to pump all the water to a level 1 foot above the top of the tank.

Simply 8x squared + 5(7x squared- x) - 2x =

What is the length of the segment, endpoints of which are intersections of parabolas y=x2? 11 4 x? 7 4 and y=? 7 8 x2+x+ 31 8 ?
