Answer:
(-3, 5) radius- r= 5
Step-by-step explanation:
x^2+6x+y^2-10y=-9
Rewrite ^2+6x+y^2-10y=-9 in the form of the standard circle equation
(x-(-3))^2+(y-5)^2= 5^2
Therefore the circle properties are:
(a, b)=(-3, 5), r= 5
1/3 as a decimal is roughly .333 repeating
Answer:
32.5
Step-by-step explanation:
The measure of an arc of a circle is half the measure of the angle that is created when two chords from the endpoints of the arc intersect on the circumference of the circle, so 65/2 = 32.5.
