Answer:

351.9 cm³

Step-by-step explanation:

The ratio of the areas of two similar solids is equal to the square of the ratio of the lengths.

A₂ / A₁ = (s₂ / s₁)²

The ratio of the volumes of two similar solids is equal to the cube of the ratio of the lengths.

V₂ / V₁ = (s₂ / s₁)³

Therefore, we can say:

V₂ / V₁ = (A₂ / A₁)^(3/2)

Plugging in values:

V / 8 cm³ = (324 cm² / 26 cm²)^(3/2)

V = 351.9 cm³

<h2><u> $\bold\color{plum}\tt \: Answer \: \: 1 :$ </u></h2>

Diameter = 4 cm

Radius = Diameter/2 = 2 cm

Area of circle :

$= \pi{r}^{2}$

$= 3.14 \times 2 \times 2$

$= 3.14 \times 4$

$= 12.56 \: {cm}^{2}$

Circumference of circle :

$= 2\pi r$

$= 2 \times 3.14 \times 2$

$= 12.56 \: \: {cm}^{2}$

<h2>Therefore, </h2><h3>Diameter = 4 cm</h3><h3>Radius = 2 cm</h3><h3>Area = 12.56 cm²</h3><h3>Circumference = 12.56 cm</h3>

<h2><u> $\bold{\color{plum}\tt \: Answer \: \: 2 :}$ </u></h2>

Circumference = 15 feet (given)

Radius :

$= 2\pi r$

$= 2 \times \frac{22}{7} \times r = 15$

$= \frac{44}{7} \times r = 15$

$= 44r = 15 \times 7$

$= 44r = 105$

$= r = \frac{105}{44}$

$= r = 2.38 \: feet$

Diameter = r×2 = 2.38 × 2 = 4.76 feet

Area :

$= \pi {r}^{2}$

$= 3.14 \times 2.38 \times 2.38$

$= 17.78 \: {ft}^{2}$

<h2>Therefore, </h2><h3>Diameter = 4.76 feet</h3><h3>Radius = 2.38 feet</h3><h3>Area = 17.78 ft²</h3><h3>Circumference = 15 feet</h3>

<h2><u> $\color{plum}\tt \: Answer \: \: 3 :$ </u></h2>

Diameter = 2 cm (given)

Radius = D/2 = 2/2 = 1 cm

Circumference :

$= 2 \pi r$

$= 2 \times 3.14 \times 1$

$= 6.28 \: feet$

Area :

$= \pi {r}^{2}$

$= 3.14 \times 1 \times 1$

Radius = 4.3 mm

Diameter = r×2 = 4.3 × 2 = 8.6 mm

Circumference :

The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $

ValentinkaMS [17]

Answer:

Future Value = $ 12528.15

Step-by-step explanation:

The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:

$Future\ Value = (Present\ Value)(1-depreciation\ rate)^n\\$

where,

Future Value = ?

Present Value = $ 24000

Depreciation Rate = 15% = 0.15

n = no. of years = 4

Therefore,

$Future\ Value = (\$ 24000)(1-0.15)^4$

<u>Future Value = $ 12528.15</u>

Factor.

Sergio039 [100]

Answer:

$4(2x^5+x^2-3)$

Step-by-step explanation:

The question is to factorize $8x^5+4x^2-12$

<em>What is common from all 3 terms?</em> It is the factor 4, so we take out 4 and write the remaining as "factorized form".

(Work shown below):

$8x^5+4x^2-12\\=4(2x^5+x^2-3)$

<u>First answer choice is right.</u>
