hello .................................................
Sphere is divided into 2 equal parts = 2 (hemisphere)
T.S.A of hemisphere = 3πr²
[it is given that the sphere is divided into 2 parts]
Therefore,
T.S.A of both hemisphere = 2 (3πr²)
T.S.A of both hemisphere = 6πr²
hence whole surface are of two part 6πr²
