Details A football is 10.8 inches from tip to tip and 7.2 inches in diameter at its thickest. The shape of the football can be modeled by the function f(x) = -0.123x² +3.6, for-5.4 ≤ x ≤ 5.4, where a is in inches. Find the volume of the football by rotating the region bounded by the graph of f about the x-axis.

The function y = 20₁1/1 + for -170 ≤ x ≤ 240, where a and 57600 y are in feet, describes the shape of such a tower (laying on its side). Determine the volume of the tower by rotating the region bounded by the graph of y about the x-axis. Volume =
