hopefully this will help you

Answer 2

Digram:

`\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 9\ cm}\end{picture}`

Given :

`\\`

• Radius of circle = 9cm
• π = 314

`\\`

To find:

`\\`

• Area of circle

`\\`

Solution:

`\\`

We know:-

`\bigstar \boxed{ \rm Area \: of \: circle = \pi {r}^(2) }`

`\\`

So:-

`\\`

`\dashrightarrow\sf Area \: of \: circle = 314 * {9}^(2)`

`\\ \\`

`\dashrightarrow\sf Area \: of \: circle = 314 * 9 * 9 \\`

`\\ \\`

`\dashrightarrow\sf Area \: of \: circle = 314 * 81 \\`

`\\ \\`

`\dashrightarrow\bf Area \: of \: circle = 25434 \: unit^2\\`

`\\ \\`

.°. Option D is correct
