Question

If the chords of circle 16 cm and situated 6 cm from circle find the diameter of circle

Answer 1

Answer: 20 cm

Step-by-step explanation:

Line from the centre bisects the chord

Half the length of chord = 8cm

The line = 6cm

Now,

By Pythagoras theorem

(8)² + (6)² = ( radius )²

64 + 36 = ( radius )²

100 = ( radius )²

Radius = 10 cm

Diameter = 2*radius

= 20 cm
