Disk Method Volume Formula

Question

The region bounded by the graph of $$y=f(x)$$ and the line $$y=0$$ over the interval $$[a, b]$$ is revolved about the x-axis. Using the disk method, which of the following gives the volume of the resulting solid?

Accepted Answer

$$V=\int_{a}^{b} \pi*(f(x))^2\,dx$$

Answer

$$V=\pi*(f(b)-f(a))$$

Answer

$$V=\int_{a}^{b} \pi*f(x)\,dx$$

Answer

$$V=\pi*\int_{a}^{b} f(x)\,dx$$
