    6pi

    Step-by-step explanation:

    Area of a circle = 2pi*r

    d = 12

    r = d/2

    r=6

    Area of semicircle = (2pi * r) / 2 = pi*r

    pi*6 = 6pi

    Answer:18π cm^2

    Step-by-step explanation:

    diameter=12

    Radius=diameter ➗ 2

    Radius=12 ➗ 2

    Radius=6

    Area of semicircle=0.5 x π x radius x radius

    Area of semicircle=0.5xπx6x6

    Area of semicircle=18π cm^2
