Question 815504
Suppose a chord of a circle is 50 cm long, and the distance from its midpoint to the center of the circle is 60 cm.
 Find the radius of the circle.
:
If you draw this out where the line bisects the chord to the center given as 60,
two right triangles are formed with legs of 60 and 25, the radius is the hypotenuse
r = {{{sqrt(60^2+25^2)}}}
r = 65 cm
