Answer: 39.58 cm

Step-by-step explanation:

The circumference of a circle is 2 times  the radius times pi or  pi times the diameter.  so we know the diameter is 12.6 so just multiply it by pie.

12.6 * pi = 39.584

Now rounded to the nearest hundredth is 39.58.

<u />You can find the area of a trapezoid with a+b/2*h. If you do so with those numbers, you will get 108.
<u>B
</u>
<u /><u />If you multiply 2.5 by 108, you can find the cost to tile the entire trapezoid. This is $270 even.
<u>C
</u>
<u />To solve for the area of a parallelogram, you can simply multiply bh. If you do so with these numbers, you will get 96.
<u>D

The slope of the tangent line for the curve r=2 cos(3 theta) where theta = pi/6 is.
Phantasy [73]

as you already know, the slope of the tangent line is simply the derivative of the function, so

r=2cos(3\theta )\implies \cfrac{dr}{d\theta }=2\stackrel{chain~rule}{\left[ -sin(3\theta )\cdot 3 \right]} \\\\\\ \left. \cfrac{dr}{d\theta }=-6sin(3\theta ) \right|_{\theta =\frac{\pi }{6}}\implies -6sin\left( 3\cdot \frac{\pi }{6} \right)\implies -6sin\left( \frac{\pi }{2} \right)\implies -6
