Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is
The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.
Therefore, the required inequality for the given graph is .
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>
