Question

what is the length of chord $overline{st}$ in $odot p$ below? a. 3.5 units b. 6.4 units c. 7 units d. 3.2 units

Explanation:

Step1: Identify circle chord property

In a circle, if two chords are equidistant from the center, they are congruent.

Step2: Match chord lengths

Chord $\overline{QR}$ is 7 units, and $\overline{ST}$ is equidistant from center $P$ as $\overline{QR}$. Thus, $\overline{ST} = \overline{QR}$.
<Expression>$\overline{ST} = 7$</Expression>

Answer:

C. 7 units
