Find the area of a compound shape<br><br> Can you please explain

gtnhenbr [62]

Answer:

$A=292.53~m^2$

Step-by-step explanation:

<u>Area of a Compound Shape</u>

The shape shown in the image is made of two shapes: Half a circle of radius 8 m and a triangle of base 24 m and height 16 m.

The area of a circle of radius r is:

$A_c = \pi r^2$

The area of a triangle of base b and height h is:

$\displaystyle A_t=\frac{b.h}{2}$

Calculate the area of the circle:

$A_c = \pi 8^2$

$A_c = 64\pi$

Area of half the circle:

$A_c/2 = 32\pi~m^2$

Area of the triangle:

$\displaystyle A_t=\frac{24\cdot 16}{2}$

$A_t=192~m^2$

The area of the shaded shape is:

$A=32\pi~m^2+192~m^2$

Substituting the value of pi:

$\mathbf{A=292.53~m^2}$

The first figure is dilated to form the second figure.

Alja [10]

1) The scale factor is 0.25 is true.

Step-by-step explanation:

Step 1:

The first figure is dilated to form the second figure. The shape is a rhombus.

It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.

Step 2:

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.

The scale factor $= \frac{1.45}{5.8} = \frac{1}{4} = 0.25.$

So the scale factor is 0.25. This is the first option.

Which of the following equations have exactly one solution?

Tems11 [23]

Answer:

A, B, & C

Step-by-step explanation:

A: -5x +12 = -12x - 12

+12x +12x

7x + 12 = -12

-12 -12

7x = -24 [Divide both sides by 7 to get x]

x = -24/7

B: −5x + 12 = 5x + 12

-5x -5x

-10x + 12 = 12

-12 -12

-10x = 0 [Divide both sides by -10 to get x]

x = 0

C: −5x + 12 = 5x − 5

-5x -5x

-10x + 12 = -5

-12 -12

-10x = -17 [Divide both sides by -10 to get x]

x = 17 / 10

D: −5x + 12 = −5x − 12

+5x +5x

12 ≠ -12 [The statement is false, so it isn't the correct answer]
