Algebra.Com's Answer #553264 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! Area(A) of circle = pi*radius(r)^2 \n" ); document.write( "Circumference of circle (C) = pi*diameter(D) \n" ); document.write( "we are given A = 32*pi, therefore \n" ); document.write( "32*pi = pi*r^2 \n" ); document.write( "divide both sides of = by pi \n" ); document.write( "r^2 = 32 \n" ); document.write( "r = square root of 32 \n" ); document.write( "now C = pi*D and D = 2r, therefore \n" ); document.write( "C = 2*pi*square root of 32 \n" ); document.write( "answer is e \n" ); document.write( " \n" ); document.write( " |
