What is the radius of a circle if it is equal in area to a triangle with an altitude of 4 and a base of 16?
\n" ); document.write( ":
\n" ); document.write( "circle area = triangle area
\n" ); document.write( "\"pi%2Ar%5E2\" = \"1%2F2\"*16*4
\n" ); document.write( "\"pi%2Ar%5E2\" = 32
\n" ); document.write( "\"r%5E2\" = \"32%2Fpi\"
\n" ); document.write( "r = \"sqrt%2832%2Fpi%29\"
\n" ); document.write( "r = \"4%2Asqrt%282%2Fpi%29\" ~ 3.19154 is the radius
\n" ); document.write( "
\n" );
