wire is in shape of semi circle of radius 28cm
so it's circumference will be perimeter of square
πr=4(side)
22/7×28=4(side)
22cm=side
so it's circumference will be perimeter of square
πr=4(side)
22/7×28=4(side)
22cm=side

Answer:
36 cm
Step-by-step explanation:
perimeter of semicircle = πr + d
= 22/7 * 28 + 56
= 88 + 56
= 144 cm
side = 144/4 cm
= 36 cm
