The length of arc FD with a radius of 15 and angle of 120° is 10π units.
An equation is an expression that shows the relationship between two or more numbers and variables.
The length of an arc is given by:
arc length = (Ф/360) * 2π*radius
Let us assume that the angle is 120°
arc FD = (135/360) * 2π(15) = 10π
The length of arc FD with a radius of 15 and angle of 120° is 10π units.
