Question

JK and LM are perpendicular diameters of a circle. They are each 12 inches long. What is the approximate length of chord LK? With Explanation Please

Answer 1

8.5 inches

Explanation:

Let the center of the circle = C

Now CK = CL = 6

Using Pythagoras theorem

LK^2 = CL^2 + CK^2

= 6^2 +6^2

= 36 + 36

= 72

LK = 72 ^1/2

= ( 36*2)^1/2

= 6(2)^1/2

= 8.5 inches
