## Main Question or Discussion Point

I need to know the Surface Area and Volume of a spherical ball at the origin radius a.

What I want is to evaluate the integrals at each integral.

##\oint_S dS =\int\int d? d? = 4 *\pi*r^2##

##\oint_V dV = \int_0^{\pi}\int_0^{2\pi}\int_0^a dr d\theta d\phi## = ##\frac{4}{3}*\pi*a^2##
