Question

A chord of length 30cm is drawn at distance of 8cm from the centre of a circle. FIND THE RADIUS​

Answer 1

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
