The area of a circle has formula:
\n" ); document.write( " $\"A+=+pi%2Ar%5E2\"$
\n" ); document.write( "However if we are given the diameter, we must find radius by dividing by 2.
\n" ); document.write( "D = 7 ft
\n" ); document.write( "r = 3.5 ft.
\n" ); document.write( "22/7 makes more sense here.
\n" ); document.write( " $\"A+=+%2822%2F7%29%2A%287%2F2%29%5E2\"$
\n" ); document.write( " $\"A+=+%2822%2F7%29%2A%287%2F2%29%2A%287%2F2%29%7D%7D%0D%0A%7B%7B%7BA+=+%2811%29%2A%287%2F2%29\"$
\n" ); document.write( " $\"A+=+%2877%2F2%29\"$
\n" ); document.write( "or 38.5 square feet. \n" ); document.write( "
