Question

the circumference of a circle is 132 cm find its area​

Answer 1

Answer:

according to question :-

circumference = 132

2πr = 132

2 * 22/7 * r = 132

r = 132*7/22*2

r = 21

area = πr^2

area = 22/7 * 21*21 = 22*3*21 = 1386cm ^2

hope you understand plz thank my answer

Answer 2

Circumference of circle = 2Pir

132 = 2×22/7×r

924 = 44×r

r = 21 cm

area of circle = Pir^2

= 22/7×21×21

= 1386 cm^2

I hope it helps you!!^_^
