Right triangle abc is located at a (−1, −2), b (−1, 1), and c (3, 1) on a coordinate plane. what is the equation of a circle a with radius segment ac?
(x + 1)2 + (y + 2)2 = 9
(x + 1)2 + (y + 2)2 = 25
(x − 3)2 + (y − 1)2 = 16
(x − 3)2 + (y − 1)2 = 25

answer:

step-by-step explanation:

use the distance formula to find the length of ac

the circle equation is in the format , with the center being at the point (h, k) and the radius being r

ac = 5, so r = 5

the center of circle a is point a, (-1,-2)

plug in these values to the circle equation.
