Area

There's a formula for the area of a circle. That formula is:


\sf{A=\pi r^2}

Where:

  • A = area
  • π = pi
  • r = radius

Diagram:


\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 15\ cm}\end{picture}

Plug in the data:


  • \sf{A=\pi*15^2}

  • \sf{A=\pi*225}

  • \sf{A=706.86\:ft^2}

Hence, A = 706.86 ft
