    Answer:

    The area of semi-circle is 2π units²

    Step-by-step explanation:

    Given that the formula of area of circle is, Area = π×r² where r represents radius of circle. Then, you have to substitue the value of radius into the formula :

    Let r = 2 units,

    A = π×2²

    = 4π units²

    The question says it is a semi-circle so you have to divide it by 2 :

    A = 4π ÷ 2

    = 2π units²

    Area of a Semi Circle: (pi x r^2)/2

    3.14 x 2^2

    3.14 x 4 = 12.56

    12.56/2 = 6.28

    Therefore, the area of a semi-circle is 6.28.
