Algebra.Com's Answer #322752 by ccs2011(207)![]() ![]() You can put this solution on YOUR website! The given area equation: \n" ); document.write( "gives the relationship between the area and radius of a circle. \n" ); document.write( "It is a direct relationship so as radius increases, so does the area. \n" ); document.write( "To find a value for A (area) you need a value for r (radius), then substitute it in. \n" ); document.write( "Given: radius = 7, pi = 3.14 \n" ); document.write( "Substitute these into \n" ); document.write( " \n" ); document.write( "Do the multiplication \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Therefore the area of a circle with radius of 7 cm. is 153.86 sq.cm. \n" ); document.write( " \n" ); document.write( " |
