    the perimeter of a semi circle = 6.28yards

    Step-by-step explanation:

    given that the diameter of semicircle = 2yards

    semicircle perimeter = ?

    π = 3.14

    recall that the formulae for calculating the perimeter of a semi circle = 1/2πd + d

    the perimeter of a semi circle = 1/2πd + d

    the perimeter of a semi circle = 1/2 x 3.14 x 2yards + 2yards

    the perimeter of a semi circle = 3.14 + 2yards

    the perimeter of a semi circle = 6.28yards
