    Vector Calculus (area II)

    Calculate the area of the cone \ z = \sqrt {x^2 + y^2}, that is inside cylinder x^2 + y^2 \leq 2x, outside the cylinder x^2 + y^2 \leq 1 and above the plane xy.

    A.: \frac {\sqrt{2} (2\pi + 3 \sqrt{3})} {6}

    Are you sure it's not asking you to calculate the VOLUME, not the area?

    Yes, I'm sure. The formula is:  A = \iint \limits_S \left ||{{\vec{r_u}.\vec{r_v}}} \right || dA

    Yes, I'm sure. The formula is:  A = \iint \limits_S \left ||{{\vec{r_u}.\vec{r_v}}} \right || dA .

    But I can't figure out the limits of integration.

    --> I'm sorry for the repeated post (how can I delete the first one?)
