Find the volume of the solid generated when the region bounded by the given curves is revolved about the indicated axis using Cylindrical Shell Method and sketch the graph. 1. An oil tank in the shape of a sphere has a diameter of 60 ft. How much oil does the tank contain if the depth of the oil is 25ft?

A. Find the x- and y-coordinates of the three points of intersection of the graphs of f and g. B. Estimate the area of R1 to three reasonable places past the decimal. C. Find the EXACT area of R2. (No calculator approximations) D. Find the exact volume of the solid formed by revolving R2 about the x-axis. (No calculator approximations)

A volume is described as follows: 1. the base is the region bounded by y = 9 – la and y = 0 2. every cross section parallel to the x-axis is a triangle whose height and base are equal. Find the volume of this object. volume =
