Answer:
radius is 28 cm
Step-by-step explanation:
1st method
perimeter = 176 cm
=> 2πr = 176 cm
=> 2 × 22/7 × r = 176
=> r = 176 × 7 / 2 × 22
=> r = 28 cm
2nd method by using another formula
perimeter = 176 cm
=> πd = 176 cm
=> 22/7 × d = 176 cm
=> d = 176 × 7 / 22
=> d = 56
now , radius = d /2 = 56 / 2 = 28 cm
