Algebra.Com's Answer #327426 by cleomenius(959)![]() ![]() You can put this solution on YOUR website! The area of a circle is pi * r^2\r \n" ); document.write( "\n" ); document.write( "25 / pi = 7.96.\r \n" ); document.write( "\n" ); document.write( "At this point, you only will need the square root of 7.96.\r \n" ); document.write( "\n" ); document.write( "This is your radius.\r \n" ); document.write( "\n" ); document.write( "2.82\r \n" ); document.write( "\n" ); document.write( "Cleomenius \n" ); document.write( " |
