the area of a cirle is 87 sq. feet, find the diameter of the circle.
\n" ); document.write( "------
\n" ); document.write( "Area = (pi)r^2
\n" ); document.write( "87 = (pi)r^2
\n" ); document.write( "r^2 = 87/pi
\n" ); document.write( "--
\n" ); document.write( "radius = sqrt(87/pi)
\n" ); document.write( "---
\n" ); document.write( "diameter = 2[sqrt(87/pi)]
\n" ); document.write( "============================
