HELP ME PLZZZZ!!!!!!!!!!!!!!!!!!

Alekssandra [29.7K]

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486

In Problems 1-8, determine the level of measurement of each variable.

lbvjy [14]

The level of measurement of each given variable are:

1. Ordinal

2. Nominal

3. Ratio

4. Interval

5. Ordinal

6. Nominal

7. Ratio

8. Interval

Level of measurement is used in assigning measurement to variables depending on their attributes.

There are basically four (4) levels of measurement (see image in the attachment):

1. Nominal: Here, values are assigned to variables just for naming and identification sake. It is also used for categorization.

Examples of variables that fall under the measurement are: Favorite movie, Eye Color.

2. Ordinal: This level of measurement show difference between variables and the direction of the difference. In order words, it shows magnitude or rank among variables.

Examples of such variables that fall under this are: highest degree conferred, birth order among siblings in a family.

3. Interval Scale: this third level of measurement shows magnitude, a known equal difference between variables can be ascertain. However, this type of measurement has no true zero point.
