Hi there! The answer is ( - 7, 5)
The standard form of the equation of a circle is the following:

In this equation r represents the radius of the circle and the point (a, b) is its centre.
Therefore, the centre of the circle

is the point ( - 7, 5).
There are 2pi radians in a circle
so the fraciton is Θ/(2pi)
so
pir^2 times Θ/(2pi)=pir^2Θ/2pi=Θr^2/2
multiply it by Θ/(2pi)
Answer:
-6/-2=3 (the answer is 3)
Step-by-step explanation:
Change in y/ Change in x. How you do it: -6-0/2-4=-6/-2=3
Hope this helped :)
