    The answer is 11.78ft

    Step-by-step explanation:

    The area for calculating the length of an arc is given as;

    Theta/360° * 2πr where;

    Theta = central angle = 75°

    r is the radius of the circle = 9ft

    Substituting the values given into the formula will give;

    Length of an arc = 75/360 * 2π (9)

    = 75/360*18π

    = 1350π/360

    = 3.75πft

    = 11.78ft (to 2 decimal places)

    The length of the arc on the circle is 11.78ft
