You can put this solution on YOUR website! If a chord of a circle of the radius 5 cm. is a tangent to a circle of radius 3 cm., both the circle being cocentric, then the length of the chord is:
:
draw this out as described, note the chord is 3 cm from the center, draw two 5" radii to each end of the chord, forming two right triangles.
Let a = half the length of the chord, use pythag here
a^2 + 3^2 = 5^2
a^2 = 25 - 9
a =
a = 4"
therefore
2 * 4 = 8" is the length of the chord
