Two fences in a field meet at 120 degrees. A cow is tethered at their intersection with a 15-foot rope, as shown in the figure. Over how many square feet may the cow graze?
\n" ); document.write( ":
\n" ); document.write( "First, find the area the cow could graze if there were no fence, just a circular area with 15' radius
\n" ); document.write( ":
\n" ); document.write( "A = pi*15^2
\n" ); document.write( "A = pi*225
\n" ); document.write( "A = 706.85 sq ft
\n" ); document.write( ":
\n" ); document.write( "The portion of the circle limited by the fence would be:
\n" ); document.write( " $\"120%2F360\"$ = $\"1%2F3\"$ * 706.85 = 235.62 sq ft \n" ); document.write( "

\n" );
