Answer 1

hope it would be helpful and correct

Answer 2

Given :-

• Shape = Circle
• Circumference of Circle = 36cm

To Find :-

• Radius of Circle

Solution :-

➞ Circumference of Circle = 2πr

➞ 36 = 2 × 22/7 × radius

➞ 36 / 2 = 22/7 × radius

➞ 18 = 22/7 × radius

➞ 18 × 7 = 22 × radius

➞ 126 = 22 × radius

➞ 126 / 22 = radius

➞ 5.72 = radius { Approx }

Thus Radius of Circle is 5.72cm { Approx }
