Algebra.Com's Answer #504961 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! The surface area of the pond is A=Pi*r^2 where r is the radius. Sooo \n" ); document.write( "A=Pi*(0.75)^2 \n" ); document.write( "A= Pi*(0.5625)=(3.14)*(0.5625) \n" ); document.write( "A=1.77 sq meters \n" ); document.write( "Let x=number of (1/10) of sq meters contained in the surface area \n" ); document.write( "(1/10)x=1.77 multiply each side by 10 \n" ); document.write( "x=(1.77)*10=(17.7)= number of (1/10)'s sq meters contained in the surface area \n" ); document.write( "Then the total length of all the fish =(5cm)*17.7=88.5 cm \n" ); document.write( "Now if the fish she chooses are 8cm then the total number of fish allowed is (88.5)/8=11.06 but since you can't have .06 of a fish the answer is 11\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
