Answer:

18.87 square cm.

Step-by-step explanation:

The area of the rectangle will be (4 + 4) * 4, since the length of the rectangle would be the diameter of the circle, and the width of the rectangle would be the radius. (4 + 4) * 4 = 8 * 4 = 32 square cm.

Then, we can calculate the area of the semicircle. The area of a circle is pi * r^2, so the area of a semicircle will be half of that. pi * (4^2) / 2 = pi * 16 / 2 = 8pi. 8 * 3.14159265 = 25.1327412 square cm.

The shaded area of the middle of the shape will then be 32 - 25.1327412 = 6.8672588 square cm.

The two triangles will have the same area. Their bases will be 14 minus the diameter of the circle, then divide that by 2 to get each separate base. 14 - 8 = 6 / 2 = 3. The heights of the triangles will be the radius of the circle, or 4 cm.

1/2 * 3 * 4 = 1/2 * 12 = 12/2 = 6. That is the area of one triangle, so the area of both triangles would be 6 * 2 = 12 square cm.

6.8672588 + 12 = 18.8672588, or 18.87 square cm.

Hope this helps!

11^2^3x=983298f+0220.2^2(38) <br> whats x.
Mazyrski [523]

Answer:

x=1638831.492383738758729e+23f+0

Step-by-step explanation:

(1123)(x)=983298f+(220.22)(38)

Step 1: Divide both sides by 8.954302432552374e+23.

8.954302432552374e+23x

8.954302432552374e+23

=

983298f+1842545.52

8.954302432552374e+23

x=

163883

19) Solve the inequality. 7x − 9 &gt; 2x + 6 A) x &gt; 3 B) x &gt; 3 5 C) x &gt; −3 D) x &gt; − 3 5
Marianna [84]

Answer:

B

Step-by-step explanation:

Given

7x - 9 > 2x + 6 ( subtract 2x from both sides )

5x - 9 > 6 ( add 9 to both sides )

5x > 15 ( divide both sides by 3 )

x > 3 → B
