Step-by-step explanation:

<h3>Input Data :</h3>

Length = 3.6 cm

<h3>Objective :</h3>

Find the volume of Hemisphere.

<h3>Formula :</h3>

Volume =

\frac{ 2\pi {r}^{3} }{3}

<h3>Solutions</h3>

volume =

<h3>\frac{2 \times 3.1416 \times 3.6 ^{3} }{3}</h3>

\frac{2 \times 3.1416 \times 46.656}{3}

\frac{293.1483}{3}

Select all expressions that can be subtracted from 9x to result in the expression 3x+5.
Arte-miy333 [17]
<h2>Answer:</h2><h2>The expressions that can be subtracted from 9x to result in the expression 3x+5 is 6x - 5</h2>

Step-by-step explanation:

To find the expression that can be subtracted from 9x to result in the expression 3x+5.

Let us consider the expression, a - b = c

Here a = 9x

the result, c = 3x + 5

b = ?

Substitute the values in the above equation, we get

9x - b = 3x + 5

9x - (3x + 5) = b

b = 6x - 5

Calculate the area of the shaded region between the regular polygons. Round to the nearest hundredth.
wolverine [178]

Answer:

I hope I'll help you with this but I am not sure of it all...

The area of the shaded region is 46,77

Step-by-step explanation:

To determine the area of the shaded hexagon, we must first calculate te area of the whole shaded hexagon and minus that by the white little hexagon.

The formula to calculate the area of a hexagon is (3√3 s2)/ 2

(where s = one side of the hexagon)

if one side a the little white hexagon equals 6 ft;

3√3 6ft.2/2 = 18√3/2 = 9√3

now for the bigger hexagon where one side is 12 ft;

3√3 12 ft.2/2 = 72√3/2 = 36√3

now the area of the bigger one minus the area of the smaller one;

36√3 - 9√3 = 46,77
