[@michaelholland5424]

The surface area of a sphere is 4pi*r^2. since a steradian is A/r^2 substitute surface area equation for A. The answer is 4pi.

[@ShreedharJadhav]

Answer is 4πr² ÷ r²
which is *4π* .

Ans: Omega = 4 pi steradians or to say 12.56 sr(approx) (if you want to imagine)
So, approx 12.56 circles can be made on the surface of a sphere whose radius is equal to that of the sphere. Hope you understood😊.

4 × 3.14 = 12.56
