Question

What is the length of chord sy in OP below?
A. 3.2 units
B. 3.5 units
O c. 7 units
O D. 6.4 units

Answer 1

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.
