The radius is 4.5 km, so a radian is 4.5 km, and the skier went 1.8 km or 0.45 radian before taking a rest.
\n" ); document.write( "x^2+y^2=20.25 (r^2)
\n" ); document.write( "The sine of 0.45 radian is 0.4350. Multiply that by 4.5 to get the y-value,1.9575
\n" ); document.write( "The cosine of 0.45 radian is 0.9004. Multiply that by x, 4.5, to get 4.052. That is the the x-value
\n" ); document.write( "(4.052,1.9575)
\n" ); document.write( "That is done because the sine is x/radius.
\n" ); document.write( "The two coordinates squared and added=20.25. \n" ); document.write( "

\n" );
