Question 1045494
find the radius of a circle with center at (2,3), if the chord of length 10 is bisected at (-3,0)
<pre>Length of perpendicular bisector from the center to the chord (one leg of right triangle with central angle as one of the vertices): {{{sqrt(34)}}}
Length of other leg of right triangle, with a value that is {{{matrix(1,3, (1/2), of, chord)}}}: 5 units
Length of radius (r), or hypotenuse of right triangle: {{{highlight_green(matrix(1,3, (sqrt(34))^2 + 5^2 = r^2, "======>", highlight(sqrt(59) = r)))}}}
