The circumference of a circle is 39.6 cm. Find its area. |
|
Answer» 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. |
