The graph of the equation below is a circle. what is the length of the radius of
the circle?
(x + 5)2 + (y + 7)2 = 212
o a. 441
o b. 42
o c. 10.5
o d. 21

D. 21.

Step-by-step explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2  where r is the radius.

Comparing:

(x + 5)^2 + (y + 7)^2 = 21^2

So r^2 = 21^2

making r = √21^2

= 21.
