Step-by-step explanation:

The domain refers to the set of possible <u>input</u> values, so in the domain of a graph consists of all the input values shown on the x-axis, in this case, all numbers beetwen -6 and -2. The range is the set of possible <u>output</u> values, which are shown on the y-axis; in the graph, all numbers equal and higher than -4.

Ede4ka [16]

Answer:

The actual area of the garden is 1256 square feet.

Step-by-step explanation:

Given:

A gardener is designing a circular garden.

On the blueprint, the garden has a diameter of 16 centimeters.

The blueprint has a scale of two centimeters to five feet.

Now, to find the actual area of the garden.

Let the actual diameter of the garden be x\ feet.

And the diameter of the garden on blueprint = 16\ centimeters.

As, given:

The blueprint has a scale of two centimeters to five feet.

2 centimeters is equivalent to 5 feet.

Thus, 16 centimeters is equivalent to x\ feet.

Now, to get the actual diameter by using cross multiplication method:

\frac{2}{5} =\frac{16}{x}

By cross multiplying we get:

2x=80

Dividing both sides by 2 we get:

x=40\ feet.

<em>Thus, the actual diameter of the garden is 40 feet.</em>

Now, to get the area of the garden we get the radius and then put the formula of area:

Radius = \frac{Diameter}{2}

Radius(r)= \frac{40}{2}=20\ feet.

Area =\pi r^2.

Area=3.14\times 20^2

Area=3.14\times 400

Area=1256\ square\ feet.

Therefore, the actual area of the garden is 1256 square feet.
