Problem 6: (6 pts): Derive the formula for the volume of a circular frustum of height $h$ and radii $a$ and $b$ using the disk method. (Hint: visualize rotating the figure below by 45° counter-clockwise and deconstructing it into a solid of revolution problem). $f(x)$ is a line segment passing through $(0, a)$ and $(h, b)$ $m = \frac{b - a}{h}$, so $f(x) = \frac{b - a}{h}x + a$ Thus $V = \int_0^h \pi [\frac{b - a}{h}x + a]^2 dx$ $= \pi \int_0^h (\frac{b - a}{h}x + a)^2 dx$ Let $u = \frac{b - a}{h}x + a$ $du = \frac{b - a}{h} dx$ $u_1 = a$ $u_2 = b$ $= \pi \frac{h}{b - a} \int_a^b u^2 du$ $= \pi \frac{h}{b - a} [\frac{u^3}{3}]_a^b$ $= \pi \frac{h}{b - a} (\frac{b^3}{3} - \frac{a^3}{3})$ $= \pi \frac{h}{b - a} (\frac{b^3 - a^3}{3}) = \frac{\pi h (b^3 - a^3)}{3(b - a)} = \frac{\pi h (a^2 + ab + b^2)}{3}$
