A= <span>π (n + 4) ^2
= </span><span>π (n + 4) (n + 4)
remember order of operations FOIL
= π (n^2 + 4n + 4n + 16)
= </span>π (n^2 + 8n + 16)
A= πn^2 + 8πn + 16<span>π
do the same for B just change the signs
B = </span>πn^2 - 8πn + 16<span>π
subtract the two
(</span>πn^2 + 8πn + 16π) - (πn^2 - 8πn + 16<span>π)
=16</span><span>πn</span>
I hope this picture helps
