Step-by-step explanation:
We know Circumference of a circle = 2πr
Where r is the radius of the circle
Circumference = 2πr (the value of π is 22/7)
88 = 2 × 22/7 × r
r = 88 × 7/44
r = 14 cms
The radius of the circle is 14 cms
We know Area of the circle = πr^2
Area = πr^2
Area of circle = 22/7 × 14 × 14
Area of circle = 22 × 2 × 14
Area of circle = 44 × 14
Area of circle = 616 cm^2
