You can put this solution on YOUR website!
Area for the circular pool is A= $\"%28pi%29r%5E2\"$ and r=34/2=17 so A= $\"%28pi%2917%5E2\"$ now the Area of the pool + the walk is A= $\"%28pi%2918.5%5E2\"$ because r in this case is (34+3)/2=18.5. now take the larger area which includes the pool +walk and subtract the pool area and that will leave the area of just the walk way. so $\"%28pi%2918.5%5E2-%28pi%2917%5E2\"$ which equals $\"%28pi%29%2818.5%5E2-17%5E2%29\"$ which equals $\"%28pi%2953.25\"$ \n" ); document.write( "
