The length of the chord ST in circle with center P is; C: 7 units
Length of Chord
We are given;
- QR = 7
- distance between center and QR = 3.2 units
- the distance between center and ST = 3.2 units.
Now, we see that the two chords are equidistant from the center of the circle and as such it means that the length of both chords must be the same.
Since QR = ST from the theorem explained above about equidistant from the center, then;
ST = QR = 7 units.
