ACT Math Question Help

<p>Hi guys, I'm having trouble with this ACT Math question taken from the booklet "Preparing for ACT 2007-2008"</p>

<p>54) For a project... Kirk is making a tablecloth for a circular table 3 feet in diameter. The finished tablecloth needs to hang down 5 inches over the edge of the table, all the way around. To finish the edge of the tablecloth, Kirk will fold under and sew down 1 inch of the material all around the edge. Kirk is going to use a single piece of rectangular fabric that is 60 inches wide. </p>

<p>What is the shortest length of fabric, in inches, Kirk could use to make the tablecloth without putting any separate pieces of fabric together?</p>

<p>F.15
G.24
H.30
J.42
K.48</p>

<p>I do not understand what the question means but from my assumption of the question, I got J. The answer is K.</p>

<p>Anyone knows how to solve this? An illustration of what the question means would help.</p>

<p>Thanks.</p>

<p>Since it is 3 feet in diameter, you need 36 inches from that. 5 inches on each edge means 10 more inches overall, leading to a total of 46. Lastly, there is one more inch needed on each side, meaning two more inches overall. This leads to a total of 48 inches, or K. </p>

<p>Essentially:</p>

<p>36 for 3 ft Table
+
10 for hang down on both sides
+</p>

<h1>2 for fabric sewn to table</h1>

<p>48 inches overall</p>

<p>Because it’s the diameter you have to add the 5in. and 1in. to both sides. So it’s 3ftx12in=36in + 5in(2) + 1in(2) = 48in</p>

<p>Wow, those were clear explanations. </p>

<p>Thanks!</p>
