The line from the center of the circle
is perpendicular to the chord and meets
at it's center. A right triangle is formed
by this line and 1/2 of the chord. The line
from the center to where the chord meets the circle
is the radius, which measures:
sqrt%284%5E2+%2B+3%5E2%29
sqrt%2816+%2B+9%29
sqrt%2825%29
5
The radius is 5 cm long
