---------------------------------------------------------------------------------
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

Minchanka [31]

Answer:

Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\

Step-by-step explanation:

We have a 4-sided triangular pyramid , where

Q=\frac{\pi}{2}*H\\P=Q*\sqrt{\frac{1}{2}+\frac{4}{\pi ^{2}}}\\Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\
