Answer:

hey mate

Explanation:

The solid angle is related to the area it cuts out of a sphere: Because the surface area A of a sphere is 4πr2, the definition implies that a sphere subtends 4π steradians (≈ 12.56637 sr) at its center. By the same argument, the maximum solid angle that can be subtended at any point is 4π sr

hope it help u
