document.write( "The Circumference of a circle is 24pi feet. Find both the area and the diameter of the circle?\r\n" );
document.write( "\r\n" );
document.write( "Solution:\r\n" );
document.write( "The formula for the circumference of a circle is \r\n" );
document.write( "C = 2*pi*r\r\n" );
document.write( "\r\n" );
document.write( "Since the circumference of the circle is 24pi feet, we have\r\n" );
document.write( "24*pi = 2*pi*r\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for r\r\n" );
document.write( "2r = 24 \r\n" );
document.write( "r = 12\r\n" );
document.write( "\r\n" );
document.write( "The radius of the circle is 12 feet.\r\n" );
document.write( "\r\n" );
document.write( "The formula for the Area of a circle is pi*r^2. Since the radius is 12, we have\r\n" );
document.write( "A = pi*(12)^2\r\n" );
document.write( "\r\n" );
document.write( "Simplify.\r\n" );
document.write( "A = pi*144\r\n" );
document.write( "A=144pi\r\n" );
document.write( "\r\n" );
document.write( "The area of the circle is 144pi square feet.\r\n" );
document.write( "\r\n" );
document.write( "The diameter is twice the radius, so the diameter is 12*2=24 feet.\r\n" );
document.write( "\r\n" );
document.write( "That's it. Please email me if you have questions or comments about the solution. \r\n" );
