i can show you that integral from 0 to pi sin theta is = 2, you can calculate it bro. Next is integral from zero to 2pi for Phi=1 term = 2. therefore 2*2pi = 4pi. are u clear after trying to integerate?

Gauss law is always useful for symmetric bodies such as sphere, cylindrical and infinite rectangular sheet. For innermost region, charge enclosed in the Gaussian surface is zero, that's why electric field is also zero. And rest of the calculation is done in the attached.

there is intergration of theta and phi.. so when we integrate sin(theta) with respect to theta ,there is limit 0 to π so we get 2 and when we integrate with respect to phi we get 2π as so overall we get 2*2π=4π..R you getting?...
