Question 946640
The distance from the center to the chord would be from the radius to the midpoint of the chord, and perpendicular to the chord. This giives us two legs of a right  triangle: A= the distance from midpoint to radius=3, and B=midpoint of chord to circle=5.  The radius corresponds to the hypotenuse of this triangle, so:
{{{A^2+B^2=C^2}}}
{{{3^2+5^2=C^2}}}  
{{{9+25=C^2}}}
{{{34=C^2}}}  Find square root of each side
{{{ sqrt(34)=C}}}=5.83 ANSWER The radius of the circle is (approx) 5.83 units
