Answer 11

let's begin with the formula of the volume of solid of revolution by cylindrical shell:
\[\huge V=2\pi \int\limits_{a}^{b}x f(x) dx\]

Answer 12

x is the distance of the representative strip from the axis of revolution
f(x) is the height of the representative strip
the horizontal strip sweeps the rectangular region left to right from x= a (the y-axis) to x =b (the x-intercept of the line)
