Answer

Surface area = 2260.8 cm²

Explanation

The surface area of a normal sphere is given as

Surface area = 4πr²

where,

π = pi = 3.14

r = radius of the sphere = 12 cm

But this sphere has the middle of the sphere as part of the surface too

Surface area = 4πr² + πr² = 5πr²

Surface area = 5 (3.14) (12²)

Surface area = 2260.8 cm²

Hope this Helps!!!
