A solid lies between two planes perpendicular to the x-axis at x = 0 and x = 48. The cross-sections by planes perpendicular to the x-axis are circular disks whose diameters run from the line y =3 to the line y = x as shown in the accompanying figure. Explain why the solid has the same volume as a right circular cone with base radius 16 and height 48. 101 The height of the solid is The radius of a circular cross section of the solid at any value of x is mme Privac y=x 48 100
