Finding electric flux across a hemisphere?

Let M be the closed surface that consists of the hemisphere:

M1: x^2+y^2+z^2=1, z≥0

and its base:

M2: x^2+y^2≤1 z=0

Let E be the electric field defined by E=(3x,3y,3z). Find the electric flux across M. Write the integral over the hemisphere using spherical coordinates, and use the outward pointing normal.

∫∫M1 E·dS= a∫b c∫d f(θ,φ) dθdφ

So, I have to find a, b, c, and d (I'm assuming the bounds for theta are 0 2pi and for phi they're 0 to pi/2, since it is a hemisphere).

I also have to find f(θ,φ) and the integrals ∫∫E·dS over M1, M2, and M.

I'm pretty lost here, any advice?
