Answer:

the area of the hexagon is approx. 187.1 in²

Step-by-step explanation:

Picture this regular polygon as being a hexagon made up of six equilateral triangles of side 12 in.  We find the area of one such triangle and then multiply that by 6 to obtain the total area of the hexagon.

One such equilateral triangle has three sides all of length 12 in, and all the interior angles are 60°.  The height of one such triangle is

h = (12 in)sin 60°, or

                  √3

h = (12 in) -------- = 6√3 in

                     2

So, with base 12 in and height 6√3 in, the area of one such equilateral triangle is

A = (1/2)(12 in)(6√3 in) = 36√3 in²

and the total area of the hexagon is 6(36)√3 in², or approx. 187.1 in²

<em>Here</em><em>,</em>

<em>diameter</em><em>(</em><em>d</em><em>)</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>cylinder</em><em> </em><em>is</em><em> </em><em>1</em><em>6</em><em> </em><em>yd</em><em>.</em>

<em>radius</em><em> </em><em>of</em><em> </em><em>a cylinder</em><em> </em><em>is</em><em> </em><em>1</em><em>6</em><em>/</em><em>2</em><em> </em><em>yd</em><em>=</em><em> </em><em>8</em><em> </em><em>yd</em><em>.</em>

<em>height</em><em> </em><em>(</em><em>h</em><em>)</em><em> </em><em>of</em><em> </em><em> </em><em>a</em><em> </em><em>cylinder</em><em> </em><em>is</em><em> </em><em>1</em><em>8</em><em>yd</em><em>.</em>

<em>now</em><em>,</em><em> </em><em>we</em><em> </em><em>use</em><em> </em><em>formula</em><em> </em><em>for</em><em> </em><em>surface</em><em> </em><em>area of cylinder</em><em>, </em>

<em>a</em><em>=</em><em> </em><em>2.pi.r</em><em>(</em><em>r</em><em>+</em><em>h</em><em>)</em>
