THe hypotenuse of the triangle is the diameter of the circle.
\n" ); document.write( "Area=28
\n" ); document.write( "Altitube (base)=4
\n" ); document.write( "equation:
\n" ); document.write( "\"A=%281%2F2%29bh\"
\n" ); document.write( "We have to find h:
\n" ); document.write( "\"28%2F2=%281%2F2%29%2A4%2Ah\"
\n" ); document.write( "2h=14
\n" ); document.write( "h=7
\n" ); document.write( "Find the diameter of the circle using pythagoren theorem:
\n" ); document.write( "\"a%5E2%2Bb%5E2=c%5E2\"
\n" ); document.write( "\"4%5E2%2B7%5E2=c%5E2\"
\n" ); document.write( "d=8.1 (rounded)
\n" ); document.write( "Try to find the area and cirmuference by yourself using \"a=pi%2Ar%5E2\" and \"c=pi%2Ad\" points given are diameter = 8.1 radius = 8.1/2
