Question 1163744

A plot of land is bounded by a 140-degree circular arc and two 80-foot radii of the samecircle.  Find the perimeter of the plot, as well as its area.
<pre>The other person is WRONG! 
<b>Perimeter:</b> {{{highlight_green(matrix(1,4, (140/360) * pi*D + 2(80), ",", or, (7/18) * pi * 2(80) + 2(80)))}}}, with D being the diameter
<b>Area:</b>      {{{highlight_green(matrix(1,4, (140/360) * pi*r^2, ",", or, (7/18) * pi * 80^2))}}}, with r being the radius.
Calculate those!!
