Pls help Identify the center and the Radius of a circle that has a diameter with endpoints at 59 and 35 class=

Respuesta :

Answer:

See below

Step-by-step 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
