Answer
Surface area = 2260.8 cm²
Step-by-step 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!!!
