QuestionIn the diagram below, a chord of length 18 centimeters is bisected by a line segment that starts at the center and is 6 centimeters from the center. What is the radius of the circle in centimeters? A. $3 \sqrt{13}$ B. $3 \sqrt{5}$ C. 10 D. 12 E. 15

Studdy Solution
Calculate the radius:
$r^2 = 81 + 36$ $r^2 = 117$ $r = \sqrt{117}$ $r = 3 \sqrt{13}$
The radius of the circle is:
$\boxed{3 \sqrt{13}}$
