Length of minor arc AB : ||
B

The length of minor arc AB is π  ft

Step-by-step explanation:

The formula of the length of an arc in a circle is L = × 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle

∵ The radius of the circle is 4 ft

∴ r = 4

∵ ∠AOB is a central angle subtended by minor arc AB

∵ m∠AOB = 50°

∴ α = 50°

Substitute the values of r and α in the rule above

∵ L = × 2π(4)

∴ L = π

∴ The length of minor arc AB is π  ft
