Answer:
Step-by-step explanation:
Use the midpoint formula:
We want to find the midpoint of the line
that has endpoints.
We simplify to get;
This finally gives:
The correct answer is A.
Point D is the midpoint of the outer circle that we aim to find the area of
The circle has a diameter of WZ and radii of WC and CZ
We know that YZ=YD=10 cm
Let DC be
and CY be 
The radius of the outer circle can be written as
or 
which we can equate to find the value of
Therefore, the radius of the circle is
And hence the area of the circle is
=324

Then we can study this problem by using the graph in the figure below. We know that if there's no any purchase, the yearly cost for a member will be $60 and for a nonmember there will not be any cost. From this, we can affirm that the cost of membership is equal to $60.
On the other hand, both members and nonmembers will pay the same price on the total game tokens purchased, this is true because of the same slope that members and nonmembers have in the equations.</span>
