Question

Radius of a circle with centre O is 10 cm. Find the distance of the chord from the centre if the length of the circle is 12 cm.​

Answer 1

Answer:

8cm

Step-by-step explanation:

Radius(OA) = 10 cm

length of chord(AB) = 12 cm

Half of the chord(AD) = 6 cm ,D is centre of the chord

To find OD

(OA)² = (OD)² + (AD)²

100 = (OD)² + 36

OD = √64

OD = 8 cm
