Question

In circle with a 12-inch radius , find the length of a segment joining the midpoint of 20-inch chord and the center of the circle

Answer 1

---------------------------------------------------------------------------------
Find half the length of the chord (from midpoint to the end point touching the circumference)
---------------------------------------------------------------------------------
20 ÷ 2 = 10 inches

---------------------------------------------------------------------------------
Formula
---------------------------------------------------------------------------------
a² + b² = c²

---------------------------------------------------------------------------------
Find the length of the segment
---------------------------------------------------------------------------------
10² + b² = 12²
b² = 12² - 10²
b² = 144 - 100
b² = 44
b = √44
b = 6.63 inches

---------------------------------------------------------------------------------
Answer: The length of the segment is 6.63 inches
