Find the surface area of the solid formed by the net. Round your answer to the nearest hundredth.
-BARSIC- [3]

Answer:

<h2>The area of the total figure is around 535.43 square centimeters.</h2>

Step-by-step explanation:

In the image attached, you can notice that all rectangles have a base of 20 centimeters.

Also, each side of the equilaterals triangles is 8 centimeters.

Notice that the height of each rectangle is equal to a side of a triangle.

Using all given vales, the area of each rectangle is

A_{rectangle}=b\times h=20 \times 8 =160 cm^{2}

The area of all rectangles is

A_{rectangles}=3(160cm^{2})=480 cm^{2}, because there are three rectangles in total.

The area of each triangle is

A_{triangle }=\frac{\sqrt{3} }{4} (8cm)^{2}  =\frac{\sqrt{3} }{4}(64cm^{2} )\\A_{triangle }=16\sqrt{3} cm^{2}

The area of both triangles is

A_{triangles}=2(16\sqrt{3}cm^{2}  )=32\sqrt{3} cm ^{2}

Now, the area of the whole figure is the sum of the area of triangles and rectangles

A_{total}=480cm^{2}  +32\sqrt{3} cm^{2} \approx 535.43 cm^{2}

Therefore, the area of the total figure is around 535.43 square centimeters.

Use the compass to construct a segment on CD that is congruent to the segment AB.
Aleonysh [2.5K]
1. Use a straightedge to draw CD so it is longer than AB.
2. Place the steel tip of the compass at A and the writing tip at B.
3. Keep the same setting on the compass and place the steel tip at C. Draw an arc that intersects CD. Name this point D.
Now they are congruent.
