Question

help??? Find the length of the diameter of a circle that has a center at Point T (3, 1) and passes through the point (1, -6).

Answer 1

use distance formula...as here,..
\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]
you will et answer..

Answer 2

its sqrt53..!!!
as under...
\[d=\sqrt{(1-3)^2+(-6-1)^2}=\sqrt{(-2)^2+(-7)^2}=\sqrt{4+49}=\sqrt{53}\]

Answer 3

will be 7. somthing..

Answer 4

The center of Circle P is located at the origin. The circumference of the circle passes through Point C (2,5).
