Question

Find the area of a circle with a circumference of 12.56 units.

Answer 1

12.55

Explanation:

Answer 2

`Area\,\,of\,\,the\,\, circle=12.56\,\, units ^2`

Explanation:

Circumference of the circle= 12.56 units

`Circumference=2*\pi * r`

As,

`\pi =(22)/(7)=3.14`

`2\pi r=12.56\\\\2* 3.14 * r=12.56\\\\6.28* r=12.56\\\\r=(12.56)/(6.28) \\\\r=2\,\,units`

Area of a circle=
`=\pi * r^2`

`=3.14* 2^2\\\\\=3.14* 4\\\\=12.56\,\, units ^2`
