APFIVE Disk Method Volume Formula
When revolving the region bounded by $$y=f(x)$$ and $$y=0$$ about the x-axis over the interval [a,b], which of the following equations correctly represents the resulting volume using the disc method? Do not use a calculator.
A
$$V=\pi*\int_{a}^{b} f(x)\,dx$$
B
$$V=\int_{a}^{b} \pi*f(x)\,dx$$
C
$$V=\int_{a}^{b} \pi*(f(x))^2\,dx$$
D
$$V=\pi*(f(b)-f(a))$$
