The surface area of the hat can be found using the formula A = 4
r.
Since the radius is half of the diameter you would divide the diameter by 2 to get a radius of 8. You then substitute r for 6 in the formula and get the surface area.
A = 46
A = 804.25

Given:
The set is
To find:
The correct option for the given set which represents the quality that is not in the given set.
Solution:
We have,
It is the set of ordered pairs. So, it is a relation.
For each x-value there is a unique y-value value. So, it is a function.
All elements are real numbers but they not distinct and they are in ordered pairs. So, the given set is not a set of real numbers.
In one to one functions each image has exactly one preimage and each preimage has exactly one image.
In the given set 4 has two preimages 3 and 4. So, the given set is not a one to one function.
Therefore, the correct options are C and D.
