'
A perpendicular drawn from the center to the chord bisects the chord and the centre is equidistant from both the chords.
perpendicular distance from chord to centre = 4
half the chord = 6
The perpendicualr distance , half the chord and radius form a right triangle. with radius as the chord.
6^2+4^2= radius ^2
36+16=radius^2
sqrt52=radius

put this solution on YOUR website!Two parallel chords each have length 12, and the distance between them is 8.
What is the radius of the circle.
:
Parallel chords of equal length are the same distance from center
Therefore they are 4 units from center
:
A right triangle is formed by dist to center (4) and half the chord length (6)
The hypotenuse of this triangle is the radius, therefore
:
r =
r =
:
r = 7.21 is the radius
