I am having so many problems with these volume problems,
1. Find the volume of a the solid obtained by rotating the region enclosed by: x = 2y and y^3 = x with y>0 about the x axis
2.Find the volume of cone of height h = 250 and a circular base with radius r = 150 First find the linear equation r = Ah + B relating r, the radius of a crosssection of the cone, to h, the height of the crosssection: r = _h + _
Now compute the volume of revolution with respect to this equation to get the volume of the cone:
3.You are an Egyptian pharoah. You decide to honor yourself with a pyramid of height h = 3250 and a square base with side s = 1910
