Find the volume of the cone, read the directions carefully!!

luda_lava [24]

Answer:

300 units^3 or 96π

Step-by-step explanation:

Volume of the cone would be:

Because the formula of finding the volume of cone is

V = πr^2 * h/3

r is the radius of the base

h is the height of the cone

π is Pi, approximately 3.142 and it is the circumference of any circle divided by its diameter

V is volume

So in this case:

V = πr^2 * h/3

V = π * 6^2 * 8/3

V = π * 36 * 8/3

V = 96π or 301.44 and round it up to 300 units^3

Hope this help :3

In a city the population is increasing exponentially at a rate of 1.6% per year.

SCORPION-xisa [38]

Answer:

37.36%

Each year it increases 1.6%.

So year 1 it increases (1+1.6%), year 2 increases (1+1.6%)^2 and so on...

so after 20 years, overall increase is found by 1.016^20 = 1.3736 or increase of 37.36%

please give thanks :)

Question number 1 You are comparing the costs of producing jewelry at two different manufacturers. Company 1 charges $3.25 per p

Assoli18 [71]

The value of x at equal total cost is 266.67

Here, we want to solve the equation to get the x-value that shows the total costs for the two companies are equal

We proceed as follows;

$\begin{gathered} 3.25x\text{ + 400 = 2.50x + 600} \\ 3.25x-2.50x\text{ = 600-400} \\ \\ 0.75x\text{ = 200} \\ \\ x\text{ = }\frac{200}{0.75} \\ x\text{ = 266.67} \end{gathered}$

In 2 years, you want to have $5000 in your savings account. Find the amount you should deposit if the account pays 3% annual int

muminat

The amount you should deposit is $4709.18

Step-by-step explanation:

The formula for compound interest, including principal sum is

$A=P(1+\frac{r}{n})^{nt}$ , where:

A is the future value of the investment/loan, including interest
P is the principal investment amount
r is the annual interest rate in decimal
n is the number of times that interest is compounded per unit t
t is the time the money is invested or borrowed for

∵ You want to have $5000 in your savings account in 2 years

∴ A = 5000

∴ t = 2

∵ The account pays 3% annual interest, compounded monthly

∴ r = 3% = 3 ÷ 100 = 0.03

∴ n = 12 ⇒ compounded monthly

- Substitute these values in the formula above

∴ $5000=P(1+\frac{0.03}{12})^{(12)(2)}$

∴ $5000=P(1+0.0025)^{24}$

∴ $5000=P(1.0025)^{24}$

- Divide both sides by $(1.0025)^{24}$

∴ P = 4709.18

The amount you should deposit is $4709.18
