A dog on a leash is tied to the corner of a yard is 10 feet by 8 feet.
\n" ); document.write( " If the leash is 12 feet long, how much area can the dog access.
\n" ); document.write( ":
\n" ); document.write( "Draw this out, find the diagonal of the yard: d = \"sqrt%2810%5E2+%2B+8%5E2%29\" = 12.8ft
\n" ); document.write( "The leash is only 12ft, so there will be small area above an arc where the dog cannot reach
\n" ); document.write( ":
\n" ); document.write( "Divide the dog access area into 3 sections, 2 right triangles and a portion of a circle.
\n" ); document.write( "Both triangles have a hypotenuse of 12, find the 3rd side of each triangle
\n" ); document.write( "Triangle 1:
\n" ); document.write( "s = \"sqrt%2812%5E2-8%5E2%29\"
\n" ); document.write( "s = 8.94 ft
\n" ); document.write( "find the area
\n" ); document.write( "A1 = \"1%2F2\"*8.94*8
\n" ); document.write( "A1 = 35.78 sq/ft
\n" ); document.write( ":
\n" ); document.write( "Triangle 2
\n" ); document.write( "s = \"sqrt%2812%5E2-10%5E2%29\"
\n" ); document.write( "s = 6.63 ft
\n" ); document.write( "A2 = \"1%2F2\"*10*6.63
\n" ); document.write( "A2 = 33.17 sq/ft
\n" ); document.write( ":
\n" ); document.write( "If we find the associated angles of these triangles, we can find the angle of the portion the circle for the 3rd area\r
\n" ); document.write( "\n" ); document.write( "Find the angle of the 1st triangle
\n" ); document.write( "Cos(a1) = \"8%2F12\"
\n" ); document.write( "a1 = 48.2 degrees
\n" ); document.write( "Find the angle of the 2nd triangle
\n" ); document.write( "Cos(a2) = \"10%2F12\"
\n" ); document.write( "a2 = 35.56 degrees
\n" ); document.write( "Find the angle of the arc in the circle
\n" ); document.write( "-----------------math error here!!!-------------------
\n" ); document.write( "90 - 48.2 - 35.5 = 6.3 degrees
\n" ); document.write( "Find the area of the portion of the circle we're interested in
\n" ); document.write( "A3 = \"6.3%2F360\"*\"pi%2A12%5E2\"
\n" ); document.write( "A3 = 7.9 sq/ft
\n" ); document.write( ":
\n" ); document.write( "Find the total area the dog can roam
\n" ); document.write( "35.78 + 33.17 + 7.9 = 76.7 sq/ft\r
