Step by step explanation:
Circumference of circle =2πr
= > 2 \times \frac{22}{7} \times r = 220=>2×

22
×r=220
= > r \times \frac{44}{7} = 220=>r×

=220
= > r = 220 \times \frac{7}{44}=>r=220×

= > r = 5 \times 7 = 35=>r=5×7=35
Therefore,radius is \bold{\red{35 \:unit}}35unit
= > area \: of \: circle = \pi {r}^{2}=>areaofcircle=πr

When take π=3.14
\bold{= > 3.14 \times 1225 = 3846.25 {unit}^{2}}=>3.14×1225=3846.25unit
Answer:
3853.53681536 units²
Step-by-step explanation:
Let radius = r
2πr=220
2 x 3.14 x r = 220
6.28 r = 220
r = 35.032 (approx.)
Area of circle = πr²
= 3.14 x 35.032 x 35.032
= 3853.53681536 units²
