If a chord 10 inches long is 5 inches from the center of a circle,
what is the radius of the circle(square root answer)?
:
A line from the center to the chord, bisects the chord, therefore you have a
right triangle, two sides = 5", the hypotenuse = the radius
r =
r =
Factor to reveal a perfect square
