Answer:
17 cm
Step-by-step explanation:
In the figure below
Chord= 30 cm and its distance from the center is 8 cm
if a perpendicular is drawn from the center to the chord, its length will remain 8 cm but,
Perpendicular drawn from the center of a chord bisects the chord
so, 30 will be divided into 15 cm
to find radius we, joined OA,
we use Pythagoras theorem, so,
OA²=OP² + AP²
OA²=8²+15²
OA²=289
OA=√289
=17 CM
