circumference of circle = 2× π×r
2 × 22/7 × r = 220
44/7 × r = 220
r = 220 × 7/44
r = 5 × 7
r = 35 cm
Area of circle = π×r²
Area of circle = 22/7 × 35 × 35
= 22 × 5 × 35
= 3850 cm²

Circumfrence of circle = 2π r

2π r= 220

2*(22/7)*r=220

2*22*r=220*7

r=35 cm

Area of circle = π r^2

(22/7)*(35)^2

3850 sqcm
