At the park there a pool shaped like a circle. A - shaped path goes around the pool. Its inner diameter is 18 yd and its outer d

Hoochie [10]

Answer:

46 gallons

Explanation:

First, we need to calculate the area of the path. This area can be calculated as the difference between the area of the outer circle and the area of the inner circle. The area of a circle is equal to

$A=\pi r^2$

Where r is the radius. For the outer circle, the diameter is 28 yd, so the radius is equal to

radius = diameter/2

radius = 28 yd/2

radius = 14 yd

Then, the area of the outer circle is

$\begin{gathered} A=(3.14)(14\text{ yd\rparen}^2 \\ \text{ A = \lparen3.14\rparen\lparen196 yd}^2) \\ A=615.44\text{ yd}^2 \end{gathered}$

In the same way, the radius of the inner circle is

radius = diameter/2

radius = 18 yd/2

radius = 9 yd

Then, the area is

$\begin{gathered} A=(3.14)(9\text{ yd\rparen}^2 \\ A=(3.14)(81\text{ yd}^2) \\ A=254.34\text{ yd}^2 \end{gathered}$

So, the area of the path is

Area path = 615.44 yd² - 254.34 yd²

Area path = 361.1 yd²

Now, we know that one gallon can cover 8 yd², so we can calculate the number of gallons as

$361.1\text{ yd}^2\times\frac{1\text{ gallon}}{8\text{ yd}^2}=45.14\text{ gallons}$

Therefore, the number of gallons is 46 because we need to round the result to a whole number.

on this american flag the width of the blue rectangle is 2/5 the width of the red and white stripes. What fraction of the area o

Gnesinka [82]

The area of the blue rectangle is 8/11 of the flag

The area of a shape is the amount of space it occupies

The width is given as:

$Width = \frac 25$

<h3>Blue region </h3>

The blue region of the American flag has a dimension of 8 by 11 stars.

So, we have:

$8 : 11 = x : \frac 25$

Where x represents the length of the blue region.

Express the ratio as fractions

$\frac{8 }{ 11} = x \div \frac 25$

Multiply both sides by 2/5

$\frac{8 }{ 11} \times \frac 52= x$

$\frac{20}{ 11} = x$

Rewrite as:

$x =\frac{20}{ 11}$

The area is then calculated as:

$Area =\frac{20}{ 11} \times \frac 25$

$Area =\frac{40}{ 55}$

Simplify

$Area =\frac{8}{ 11}$

Hence, the area of the blue rectangle is 8/11 of the flag

A triangle has a perimeter of 66 feet. If the three sides of the triangle are n, 3n+3, and 4n - 9, what is the length of each si

horrorfan [7]

Answer:

9, 30, 27

Step-by-step explanation:

To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.

So, we must add the sides to get 66 feet.

n+3n+3+4n-9=66

Combine like terms, and solve:

(n+3n+4n)+(3+-9)=66

8n+-6=66

8n-6=66

n=9

So if n=9, we can easily find the value of the other sides.

3(9)+3=30 feet.

4(9)-9=27 feet

So, the sides are 9, 30, and 27 feet (in order).
