If the radius of the circle is 6 cm, what is the length of the chord whose distance from the center is 4 cm?

Sagot :

Answer:

6/2=3. The midpoint of the chord is 3cm from each point on the chord that touches the circle, and 4 cm from the centre of the circle. Call the distance from the midpoint to the centre m, and half the chord length x. So m=4, and x=3.
