There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi

The above represents a function, because the y-values have different x-values
However, the following ordered pair is not a function

The reason is that:
y-values 9 and 8 have the same x-value (3)
