Can someone please help me with this question?(adsbygoogle = window.adsbygoogle || []).push({});

x = 1-sint, y = 2+cost, rotate about y = 2

Find the surface area of the parametric curve.

I don't know how to do it with y=2, I only know how if the question askes for rotating about the x-axis.

The answer to the question is 2(pi)^2.
