A Simple and Fun Geometry Problem
<p>Here’s a math puzzle about Thanom’s roll of paper. Hmm, perhaps he has made a mess in the kitchen!? </p>
<p>Here’s a hint: a diagram will come in handy …</p>
<p><strong><em>I recommend you pause the article, grab your pen and paper, and give this a go. When you are ready, keep reading for the solution! </em></strong></p>
<h1>Solution</h1>
<p>We are given that the diameter of the roll is 12 and the diameter of the inner tube is 4.</p>
<p>That means they have radii 6 and 2respectively. <strong>The area of the inner tube is therefore 2²pi = 4pi</strong>. (This is crucial as we will see.)</p>
