Determine the area of the shaded region. Use 3 for pi.

IrinaK [193]

Answer:

The area of the shaded region is 294 square inches ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- From the attached figure

- There are two congruent circles inscribed in a circle

∵ The two congruent circles touch each other at one point and

each one touch the big circle at one point

∴ The centers of the three circles and the touches' points lie on

the same segment which is the diameter of the big circle

∴ The diameter of the big circle = the sum of the diameters of the

inscribed circles

∵ The radii of the congruent circle = 7 inches

∵ The diameter of a circle is twice its radius

∴ The diameter of each inscribed circle = 2 × 7 = 14 inches

∴ The diameter of the big circle = 14 + 14 = 28 inches

∵ The radius of a circle is half its diameter

∴ The radius of the big circle = 1/2 × 28 = 14 inches

- The area of the shaded part is the difference between the area

of the big circle and the sum of areas of the congruent circles

∵ The area of a circle = πr²

∵ The radius of the big circle is 14 inches

∵ π = 3 ⇒ given

∴ The area of the big circle = 3(14)² = 588 inches²

∵ The radius of each congruent circle is 7 inches

∴ The area of each congruent circles = 3(7)² = 147 inches²

∴ The area of the two congruent circles = 2 × 147 = 294 inches²

∵ Area shaded = area big circle - area two congruent circles

∴ Area shaded = 588 - 294 = 294 inches²

* The area of the shaded region is 294 square inches

A juice container can hold 96 ounces. The container has 72 ounces of juice. What percentage is not in the container.

Ede4ka [16]

Answer:

25% of the juice is not in the container.

Step-by-step explanation:

We are given the following in the question:

Total juice container can hold = 96 ounces

Amount of juice in container = 72 ounces

Amount of juice not in container =

$96-72=24\text{ ounces}$

We have to find the percentage of juice not in the container.

Percentage =

$=\dfrac{\text{Amount of juice not in container}}{\text{Total amount the container can hold}}\times 100\5\\\\=\dfrac{24}{96}\times 100\%\\\\=25\%$

Thus, 25% of the juice is not in the container.

Compare the graphs of the inverse variations. y=1/x and y=2.5/x

stellarik [79]

Answer:

The graph of

$y = \frac{2.5}{x}$

us a vertical stretch of the graph of

$y = \frac{1}{x}$

by a factor of 2.5.

Step-by-step explanation:

The given functions are

$y = \frac{1}{x}$

and

$y = \frac{2.5}{x}$

The graph of

$y = \frac{1}{x}$

is the parent rational function.

The graph of

$y = \frac{2.5}{x}$

is a vertical stretch of the parent rational function by a factor of 2.5
