Question

Pls help!!

Identify the center and the Radius of a circle that has a diameter with endpoints at (-5,9) and (3,5)

Answer 1

See below

Explanation:

The CENTER will de directly between the two given points

h, k = -1,7

so...so far the circle eq is

(x+1)^2 + ( y-7)^2

the RADIUS is 1/2 of the distance between the given points

1/2 d = (using distance formula) = 1/2 sqrt 80 = 4.472

then the equation of the circle in standard form

(x+1)^2 + (y-7)^2 = 20
