The formula for circumference is
\n" ); document.write( "\"C+=+2%2Api%2Ar\"
\n" ); document.write( "From above , we get
\n" ); document.write( "\"25+=+2%2Api%2Ar\"
\n" ); document.write( "dividing by 2pi, we get
\n" ); document.write( "\"25%2F%282%2Api%29+=+r\"
\n" ); document.write( "This means that
\n" ); document.write( "\"r+=+3.979\" inches and the diameter is
\n" ); document.write( "\"d+=+7.958\" inches
\n" ); document.write( "
