Because empty set has no element which automatically make it a subset of every set.

Answer:
1936 π square units
Step-by-step explanation:
Given the information:
<em>The circumference of a great circle of a sphere is 44π.</em>
As we know the formula used to find a circle's circumference is:
C = 2πr , where r is the radius of the circle
In this situation, we know C = 44π
<=> 2πr = 44π
<=> r = 22 units
Hence, the Surface Area of the sphere
S.A = 4π
= 4π
= 1936 π square units
I believe the the answer is k=192 if i am wrong I am very sorry
