The point that lies on the perpendicular bisector of AB is point N
<h3>How to determine the point?</h3>
The circle is given as:
Circle N
The chord is given as:
Chord AB
The perpendicular bisector of the chord is any line drawn from the center of the circle that divides the chord in equal halves.
This means that the point starts from point N
Hence, the point that lies on the perpendicular bisector of AB is point N

Answer:
15π/2 ft
Step-by-step explanation:
Arc length is given by the formula ...
s = rθ . . . . . r = radius; θ = central angle in radians
A 135° arc has a radian measure of (135)(π/180) = 3π/4. The radius of a circle with a 20 ft diameter is (20 ft/2) = 10 ft. So, the arc length is ...
s = (10 ft)(3π/4) = 30π/4 ft = 15π/2 ft
The answer is -4 final answer
