Calculus help

I need help with these problems.

1.)Find the surface area by revolving r=1+cos theta about the x-axis.

2.) Write the equation of the hyperbola 9x^2-4y^2-36x+24y-36=0 in the standard form. Find its vertices, foci, asymptotes, and intercepts.

3.)Find the area of the region between the curves r=2 cos theta and r=2 sin theta.
 
Hola,

Here is the answer for #1:

] 90
Surface area = 2 pi (integral) ] (1+cos theta)
] 0

don't have table of integrals to complete it though.


;)

ps. its not lining up properly when posted but you understand the way its supposed to be
