The length of diameter can be calculated by using formula;
d = [(x2-x1)2 + (y2-y1)2]1/2
(x1, y1) = (2, 3 )
(x2, y2) = (-4, -5)
d = [ (-4-2)2 + ( -5- 3)2 ]1/2
d= [ 100]1/2
d= 10
Radius = diameter / 2 = 5
The mid point of the circle can be calculated as;
M.P = [(x1 + x2)/2, (y2 +y1)/2]
M.P = [(2 - 4 )/ 2, (3-5)/2]
M.P = (-1, -1)
The standard equation of circle is;
(x-*-1)2 + (y-*-1)2 = 52
(x + 1)2 + (y + 1)2 = 25
d = [(x2-x1)2 + (y2-y1)2]1/2
(x1, y1) = (2, 3 )
(x2, y2) = (-4, -5)
