the question does not present the picture, but this does not interfere with the resolution

we know that

the axis of the sphere passes through its center, therefore the axis is equal to the diameter of the sphere

so

the diameter of a sphere=16 units

radius of a sphere=16/2-----> 8 units

the surface area of a sphere=4*pi*r²----> 4*pi*8²----> 256*pi units²

the answer is

256*pi units²
