Let the region R be the area enclosed by the function f(x)= = 3x² and g(x) = 4x. If the region R is the
base of a solid such that each cross section perpendicular to the x-axis is an isosceles right triangle with a
leg in the region R, find the volume of the solid. You may use a calculator and round to the nearest
thousandth.

Let the region R be the area enclosed by the function f(x) = ex — 1, the horizontal line y = -4 and
the vertical lines x = 0 and x = 3. Find the volume of the solid generated when the region R is revolved
about the line y = -4. You may use a calculator and round to the nearest thousandth.
