The volume of a compound shape . 10 cm & 12 cm .

The Volume Of A Compound Shape . 10 Cm & 12 Cm .

Answers

Answer 1

Answer:

total volume = (1150/3)pi cm^3

approximate total volume = 1204 cm^3

Step-by-step explanation:

The compound solid looks like it's made up of a cylinder with a base with 10 cm diameter and height of 12 cm and a half sphere with radius 10 cm.

volume of cylinder: (pi)(r^2)h

volume of sphere: (4/3)(pi)r^3

total volume = (pi)(r^2)h + (1/2)(4/3)(pi)r^3

We are given a diameter of 10 cm, so the radius is 5 cm since r = d/2.

total volume = (pi)[(5 cm)^2](12 cm) + (2/3)(pi)(5 cm)^3

total volume = 300pi cm^3 + (250/3)pi cm^3

exact total volume = (1150/3)pi cm^3

approximate total volume = 1204 cm^3

A triangle has angle measures of 95° and 65° What is the measure of the third angle
​

Answers

The third angle is 20°. This is because you add the two angles you have already (95+65) and then you subtract that from 180. In simplier words: If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.

The volume of a cylinder is 471 cm? If the
height is 6 cm, calculate the radius.

Someone plz help

Answers

Answer:

Step-by-step explanation:

Formula for volume of a circle: V=πr²

If you multiply the circle by height, it becomes a cylinder.

Formula for volume of a cylinder: V=πr²h

Plug in the numbers and get r by itself:

471 = πr²(6)

Divide both sides by 6:

78.5 = πr²

Divide both sides by π:

25 = r²

Square root both sides:

[tex]\sqrt{25}[/tex] = [tex]\sqrt{r} \\[/tex]²

5 = r

Work out h, the height of the triangular cross section.
h
7 cm
4 cm

Answers

Answer:

the height is 2.5 cm

Step-by-step explanation:

The computation of the height of the triangular section is shown below:

As we know that

Volume = One-half × base × height

35 = One-half × 4 × height × 7

So, the height is 2.5 cm

Answer:

Height = 2.5cm

Step-by-step explanation:

Volume = Base(b) x Height(h) x Length(l) / 2

Substitute the information that you have into the equation

Volume = 4 x Height(h) x 7 / 2

Height = 4x7 / 2

= 14cm

35 / 14

= 2.5cm

Subtract – 2.2 + 3x – 9 from 8x2 + 10x – 10.

find surface area of this cone ​

Answers

Answer:

SA = 200π cm²

Step-by-step explanation:

The surface area is calculated as

SA = area of base + area of curved surface

     = πr² + πrs ( r is the radius and s the slant height )

Using Pythagoras' identity in the right triangle to find s

s² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )

s = [tex]\sqrt{289}[/tex] = 17

SA = π × 8² + π × 8 × 17

      = 64π + 136π

      = 200π cm²

Answer:

The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.

Step-by-step explanation: i got it right on the test

A sample is said to exhibit undercoverage bias, if some of the portion or category of the population are not adequately represented or exempted from the selected sample. Hence, undercoverage bias exists because, The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.

Undercoverage bias produces non - representative samples as some category of the population may have been exempeted from the study. Hence, option C is correct.

Undercoverage translates that the opinion of some members of the population were not even considered. Hence, the introduction of undercoverage bias.
