Question

the radius of a circle is 15 cm and the length of perpendicular draw from it's center to a chord is 9 cm calculate the length of chord.​

Answer 1

a2+b2=c2

92+x2=152

By now you might be able to spot the 3–4–5 multiple Pythagorean triple. If not, just do the math.

81+x2=225

x2=144

x=12

Therefore, the length from the midpoint of the chord to the center is 12 cm.
