Volume of revolution at line x=-4

In summary, the volume of revolution at line x=-4 refers to the volume of a solid generated by rotating a two-dimensional shape around the vertical line x=-4. It is calculated using the formula V = &pi;∫<sub>a</sub><sup>b</sup>(f(x))<sup>2</sup> dx and has various applications in engineering, physics, and mathematics. It differs from other volume calculations as it involves rotation around a specific line and cannot have negative values.

Homework Statement



Find the volume of the solid obtained by rotating the region bounded by the curves y=0,y=sin(6x),x=6,x=0 about the axis x=−4.


Homework Equations



cylindrical method? circumference*thickness*height


The Attempt at a Solution



So I'm not sure how to write the integral when it rotates along the line x=-4 ..would it be like 2*pi*(-4+x)dx*sin(6x)? or 2*pi*(4-x)dx*sin(6x)? Or something completely different?
