    (11/3) * pi

    Step-by-step explanation:

    what circle is how bigger?

    360/110=36/11

    11pi * (36/11)

    36pi

    radius is 6 (A=r^2*pi) (36 is 6^2)

    circumference of a circle is 2pi*r

    2pi*6

    12pi

    what fraction of the circumference is 110?

    110/360=11/36

    9132/36) * pi

    (11/3) * pi
