It look like that.
Diameter = 2 so the radius = 1/2 * diameter = 1in

Volume of the cylinder = pi r^2 h

where h = height of the cylinder = 9 in

so volume = pi * 1^2 * 9 = 28.27 in^2 to nearest hundredth

Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.

elixir [45]

Answer:

She would need $4\frac{3}{8}$ flour to make $2\frac{1}{2}$ times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = $1 \frac{3}{4}\ cups$ of flour.

So, to make $2\frac{1}{2}$ times the recipe she would need = $1 \frac{3}{4}\times 2\frac{1}{2}$ .

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

$=\frac{7}{4}\times \frac{5}{2}$

$=\frac{35}{8}$

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

$\frac{35}{8}=4\frac{3}{8}$

So, she would need $4\frac{3}{8}$ flour to make $2\frac{1}{2}$ times the recipe.

None of your answers are correct

all you have to do it look at what place the value underlined

for example, find value of 5 in 517,849

the 5 is in the 100 thousands place this means that the value is 500,000

Use long division to determine the decimal equivalent of fraction with numerator 2 and denominator 3. 0 point 6 bar 0 point 7 ba

VikaD [51]

Answer:

The correct answer is A

$0.\bar6$

Step-by-step explanation:

We want to determine the decimal equivalence of $\frac{2}{3}$ .

We perform the long division as shown in the attachment.

Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is $2$ , will be inside the long division sign.

We see that the quotient of our long division is $0.6666...$ .

We can rewrite this as $0.\bar6$

Therefore $\frac{2}{3}=0.\bar6$ .
