The length of the chord is 21.21 inches.
What is Chord?
A chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.
The given parameters are:
Central angle, x = 90
Radius, r = 15 inches
The chord length (L) is calculated by:
L = 2 X r X sin(x/2)
Substitute known values
L = 2 X 15 X sin(90/2)
L = 30 X sin 45⁰
L = 30 / √2
L = 21.21 inches
Thus, the length of the chord is 21.21 inches
