Question 287908
what is the length of the diameter of a circle if the endpoint have the coordinates (-1,-1) and (2,3)

{{{ length = sqrt((x2-x1)^2 + (y2-y1)^2) }}}
{{{ length = sqrt((2 - -1)^2 + (3 - -1)^2) }}}
{{{ length = sqrt(3^2 + 4^2) }}}
{{{ length = sqrt(9 + 16) }}}
{{{ length = sqrt(25) }}}
{{{ length = 5 }}}
