Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is 
, where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
Answer:
90
Step-by-step explanation:
supplementary angles equal 180 degrees and 90+90=180
