A cylinder has a base diameter of 12in and a height of 17in. What is its volume in cubic in, to the nearest tenths place?

Anna35 [415]

Answer:

1922.7 cubic inches

Step-by-step explanation:

The volume of a cylinder can be found with this formula:

V=πr^2h

The radius, r, is half the diameter.

So, 12/2=6

r=6 inches

Then, just plug the numbers in.

V=π(6)^2(17)

V=1922.65

Rounding to the nearest tenth:

V=1922.7 cubic inches

You invest $25/month at a rate of 3.25% APR compounded monthly for 30 years. What is the total interest earned and final balance

VikaD [51]

The total interest earned is 40.75 and the final balance is 65.75

<u>Solution:</u>

Given, principle amount P = 25

Interest rate $r = 3.25\% = \frac{3.25}{100} = 0.0325$

Times compounded per year n = 12

Time in years t = 30

$Amount \ A=P\left(1+\frac{r}{n}\right)^{n t}$

On substituting the values we get

$A = 25 [ 1+ \frac{0.0325}{12}]^{12\times30}= 25 [2.63]= 65.75$

Interest I = A - P [since, A = P+I]

$\Rightarrow 65.75 - 25= 40.75$

Leon is using the recipe shown.

stira [4]

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.

Step-by-step explanation:

Given,

Olive oil used in recipe = 23 cups

Cinnamon used in recipe = 2 teaspoons

Ratio of cinnamon to olive oil in recipe = 2:23

Cinnamon Leon has = 1 teaspoon

Let x be the olive oil.

Ratio of available cinnamon to olive oil = 1:x

Using proportion;

Ratio of cinnamon to olive oil in recipe :: Ratio of available cinnamon to olive oil

$2:23::1:x$

Product of extreme = Product of mean

$2*x=23*1\\2x=23$

Dividing both sides by 2;

$\frac{2x}{2}=\frac{23}{2}\\x=11.5$

11.5 can also be written as $11\frac{1}{2}$

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.
