In a circle with a 12-inch radius, find the length of a segment joining the mid-point of a 20 inch cord and the center of the ci
borishaifa [10]

The length of the segment is 6.63 inches

Explanation:

Given that the radius of the circle is 12 inches.

The center of the circle to the endpoint and the midpoint of the chord forms a right angled triangle.

The hypotenuse is 12 inches.

One of the sides is \frac{20}{2}=10

Applying the Pythagorean theorem, we have,

a^2+b^2=c^2

Where a=x, b=10 and c=12

Thus, we have,

x^{2} +10^2=12^2

Simplifying, we get,

x^{2} =144-100

x^{2} =44

Taking square root on both sides of the equation, we have,

x=6.63

Thus, the length of the line segment is 6.63 inches.
