Okay, first we need to calculate the area of the rectangle.

Area of Rectangle- 16 x 6 = 96

Next, we need to calculate the area of the semicircles.

Formula: Radius x Radius x pi (3.14) = Area of circle

Since we know that the diameter is 6 we can figure out the radius.
The radius is half of the diameter. So our radius is 3.

3 x 3 x 3.14 = 28.26

Since it's a semi circle we now need to divide by 2.

28.26 divided by 2 = 14.13

Then, we add.

Area of rectangle
+
Area of 2 semi circles

96 + 14.13 + 14.13 = Total Area of The Figure

So our answer is 124.26

In which quadrant will θ lie if csc θ > 0 and cos θ < 0?

musickatia [10]

$\csc\theta=\dfrac{1}{\sin\theta}$

We know:

$\sin\theta > 0$ in I and II quadrant

$\cos\theta < 0$ in II and III quadrant

Therefore your answer is:

<h3>θ is in II quadrant</h3>

In a grid of a backyard, the vertices of the floor of a shed are (20, 80), (50, 60), (50, 20), and (20, 20). The coordinates are

sdas [7]

Answer:

The area of the floor of the shed is <u>1500 square feet.</u>

Step-by-step explanation:

Given:

The vertices of the floor of a shed are: (20,80), (50,60), (50,20) and (20,20)

Let us plot the given vertices on a graph.

From the graph, it is clear that the given figure is a trapezium with opposite parallel sides being parallel to the y axis. The height of the trapezium is the side that is parallel to x axis.

The area of the trapezium ABCD is given as:

$A=\frac{1}{2}(AB+CD)\times AD$

From the graph, AB = 60 ft, CD = 40 ft, AD = 30 ft

Therefore, the area is given as:

$A=\frac{1}{2}(60+40)\times 30\\A=\frac{1}{2}\times 100\times 30=1500\ ft^2$

Therefore, the area of the floor of the shed is 1500 square feet.
