Find the length of the radius of the given circle.
(x - 5)2 + (y + 3)2 = 25

  • Math -

    The standard equation of a circle with center C ( h , k ) and radius r is as follows:

    ( x - h )^ 2 + ( y - k )^ 2 = r ^ 2

    In your case r = sqrt( 25 ) = + OR - 5

    Length can't be negative so r = 5
