Answer:
the perimeter of a semi circle = 6.28yards
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
