Question

the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle​

Answer 1

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).

Answer 2

Answer:

13

Step-by-step explanation:

radius of the circle​ (r) = √12²+5² = √169 = 13
