in a circle, a chord 14 units long is drawn 3 units from the center of the origin.
what is the length of the radius to the nearest 10th
:
If you draw this out, you can see that the chord, two radii from the ends of the
chord and line from the midpoint of chord to the center, form two right angle
triangles, the radii are the hypotenuses
:
r^2 = 7^2 + 3^2
r^2 = 49 + 9
r =
r = 7.6 units
