Step-by-step explanation:
Given: Circumference of the circle = 39.6 cm. We know, Circumference of circle = 2πr Where, r = Radius of the circle ⇨ 2πr = 39.6 r = 39.6/2π r = 6.3 (put value of π = 22/7) Area of the circle = πr2 Where, r = radius of the circle ⇨ Area of the circle = π(6.3)2 = 124.74 So, area of circle is 124.74 cm2.Read more on Sarthaks.com - https://www.sarthaks.com/713826/the-circumference-of-a-circle-is-39-6-cm-find-its-area

Answer:
Area of circle = 124.74 cm²
Step-by-step explanation:
circumference of circle = 2πr
39.6 = 2πr
2 x 22/7 x r = 39.6
44r = 39.6 x 7
r = 277.2/44
r = 6.3 cm
Area of circle = πr²
= 22/7 x (6.3)²
= 22/7 x 36.69
= 873.18/7
= 124.74 cm²
