I understand that in this problem you are trying to find the radius of a pie, knowing that a 2-radian slice has an area of 10 square meters.
\n" ); document.write( "That is quite a large pizza! Or is it apple pie?
\n" ); document.write( "A whole circle of radius \"r\" has an area equal to
\n" ); document.write( "\"A=pi%2Ar%5E2\"
\n" ); document.write( "and, taken as an angle, measures, in radians, \"2pi\"
\n" ); document.write( "So the area of a 2-radian slice is
\n" ); document.write( "
\n" ); document.write( "So if \"r%5E2=10m%5E2\", then, in meters, \"r=sqrt%2810%29\",
\n" ); document.write( "or approximately 3.16 meters.
