We know that,
Circumference of a circle=2πr
➡2πr=88
➡πr=88/2
➡πr=44
➡r=44÷22/7
➡r=7×2
➡r=14 cm
Now, area of circle=πr²
↪22/7×14×14
↪616 cm²=Answer

Answer:
Area of the circle is 616 cm²
Step-by-step explanation:
Given
Circumference of the circle = 88 centimetres
To find : area of the circle
The formula for Circumference of a circle = 2πr
Radius of the circle = r
According to the question
2πr = 88 cm
2 × 22/7 × r = 88 cm (π = 22/7)
44/7 × r = 88 cm
r = 88 × 7/44
r =14 cm
Radius of the circle is 14 centimetres
Formula for Area of a circle = πr²
So,
22/7 × 14²
= 22/7 × 14 × 14
= 616 cm²
Area of the circle is 616 cm²
