Consider the surface of revolution of the curve $$y = x^2$$ where $0 < x < 1$. By writing a suitable integral, show that the area of this surface is 3.81 units. (You are advised to work in cylindrical polar).

    A surface of revolution lives in $3$-space with coordinates $x$, $y$, $z$. What is the axis of revolution in your case? What is the plane containing the curve $y=x^2$ with respect to the axis of revolution?2012-12-02
