A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?

1 answer:

6 0

The area of a square is the side of the square squared or A= s^2 (s meaning side of the square)
Perimeter or the 4 sides is P= 4 x s
Since the area is 6561, plug that into the area formula so you get 6561= s^2
Next, take the square root of both sides of the equation because that is the opposite of squaring a number)
When you do that you get s = 81
Now that you know s, plug it into the Perimeter formula P= 4 x 81
The perimeter or distance around the park is 324 meters.

Answer:

<h3>D. The amount of rotation of one side.</h3>

Step-by-step explanation:

We need to explain the statement " What affects the size of an angle? ".

Given options are

A. The length of its sides

B. The direction of one side

C. Its orientation in space

D. The amount of rotation of one side.

The correct option would be :

<h3>D. The amount of rotation of one side.</h3>

<em>Because as the one side rotated, it makes a greater or smaller arc between the two lines. That would affects the size of an angle. </em>

The diagram shows the dimensions of a teepee. Find the volume of the building to the nearest cubic unit. Use 3.14 for pi.

LekaFEV [45]

The volume of a cone uses the following formula:

$V = \pi r^{2} \frac{h}{3}$

Our diameter is 20 feet, so divide this by 2 to find the radius:

$20 \div 2 = 10$

We now have all of our values need to fill in the formula. Plug in these values:

$\pi = 3.14, r = 10, h = 17$

$3.14 * 10^{2} * \frac{17}{3}$

$3.14 * 100 * 5.67$

$314 * 5.67 = 1780.38$

The volume of the cone is 1780 cubic feet.

Answer:

b. You would conclude that the differences in the average scores can be traced to differences in the working memory of the two groups.

Step-by-step explanation:

Though the average scores of the two sets could have lead to various conditions, but retentive ability deminishes with respect to an increase in age. With respect to the age of the elderly people involved, it is expected that some of them would not be able to retain information for a long period of time. Thus, their average score is 72%.

The college students' are younger, so it is expected that they should be able to retain more information. That ability is one of the reasons why their average score is 85%.

It can be concluded from the research that the differences in the average scores is probably due to the working memory of the two groups.
