Answer
Length of arc DB = 44 feet
Step-by-step explanation
To find the length of the arc DB, we need to first note that the length of an arc is calculated using the formula
where
θ = Angle subtended at the center of the circle by arc DB = 180° - 40° = 140°
π = pi = (22/7)
r = Radius of the circle = 18 feet
