Answer:
[tex]Area\,\,of\,\,the\,\, circle=12.56\,\, units ^2[/tex]
Step-by-step explanation:
Circumference of the circle= 12.56 units
[tex]Circumference=2\times\pi \times r[/tex]
As,
[tex]\pi =\dfrac{22}{7}=3.14[/tex]
[tex]2\pi r=12.56\\\\2\times 3.14 \times r=12.56\\\\6.28\times r=12.56\\\\r=\dfrac{12.56}{6.28} \\\\r=2\,\,units[/tex]
Area of a circle= [tex]=\pi \times r^2[/tex]
[tex]=3.14\times 2^2\\\\\=3.14\times 4\\\\=12.56\,\, units ^2[/tex]
