Cicumference of a circle = 2πr
now, we have to find radius
2πr = 17.6
2 x 22/7 x r = 17.6
r = 17.6 x 7 / 2 x 22
r = 2.8 cm
now we will find area
Area of circle = πr²
⇒ 22/7 x r²
⇒ 22/7 x (2.8)²
⇒ 22/7 x 7.84
⇒ 24.64
so, the are of circle is 24.64 cm
now, we have to find radius
2πr = 17.6
2 x 22/7 x r = 17.6
r = 17.6 x 7 / 2 x 22
r = 2.8 cm
now we will find area
Area of circle = πr²
⇒ 22/7 x r²
⇒ 22/7 x (2.8)²
⇒ 22/7 x 7.84
⇒ 24.64
so, the are of circle is 24.64 cm

Step-by-step explanation:
Circumference =17.6cm
Fomula=circum. Of circle =2Pi r
176/10=2×pi×r
176/10=2×22÷7×r
176/10×1/2×22/7=r
R=2.8
Area=pi ×r^2
22/7×(28/10)^2
22/7×784/100
22×112/100
24.64
I hope thus will help u all
