<em>The area of a circle is calculated with the formula: </em>
<em>Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.</em>
<em>The radius is given as 3 inches</em>
Area = cubic inches = 28.3 cubic inches
------------------------
<em>Perimeter is calculated with </em><em>.</em>
<em>But this is 3/4 of a circle with an additional two 3-inch sides</em>
Perimeter = + 2(3) = 14.1 + 6 = 20.1 inches
