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
