Answer:
we know that
the equation of the circle is of the form
(x-h)^2+(y-k)^2=r^2
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
(x+5)^2+(y-k)^2=r^2
so
the center is the point (-5,3)
the radius is 4 units
therefore
the answer is
The radius of the circle is equal to 4 units
Half of the total members are men. For every on women there is one man.
So if there was a total of 100 people in the library and the ratio of man to women was 1:1 there would be 50 women and 50 men.
It represente the absolute value
