<em>48.984 meters</em>

Step-by-step explanation:

The distance around a circle is called the circumference, the formula for the circumference is...

$C=\pi d$

$C=2\pi r$

Since we have the diameter we will be using the first one.

$C=3.14*15.6$

$C =$

<u>48.984 meters</u>.

After giving 16 coins to Melissa, Juan had twice as many coins as Melissa. If they had 144 coins altogether, how many coins did

dem82 [27]

Melissa tem 16 moedas

Juan tem o dobro, ou seja, 16 x 2 = 32

Na adição vai ser o mesmo resultado

16+16=32

Se eles juntos tivessem 144 moedas.

Calculando

144 ÷ 2 = ou seja dividido por duas pessoas sendo melissa e juan

R = juan tem 72 moedas.

Cada um vai ficar com 72 moedas

Help ASAP!

Tema [17]

Answer:

Step-by-step explanation:

$\boxed{area \: of \: sector = \frac{1}{2} {r}^{2} θ }$

Radius= diameter ÷2

r= 32 ÷2

r= 16

$\frac{1}{2} {r}^{2} θ = \frac{512\pi}{3}$

Substitute r= 16,

$\frac{1}{2} ( {16}^{2} )(θ) = \frac{512\pi}{3}$

$128 \: θ = \frac{512\pi}{3} \\ θ = \frac{512\pi}{3} \div 128 \\ θ = \frac{512\pi}{384}$

Divide the denominator and numerator by 128:

$θ = \frac{4\pi}{3}$

Thus, the answer is B.

Subtract the 45 minutes they were eating from 1:45pm since that’s when they arrived. You now have 1:00pm, you now just need to find out how long it is from 10:20 am to 1:00pm. HINT: it’s 2h 40m

A. Transform F using the rule (x, y) → (-x, y) (1 pt.)

serg [7]

Answer:

A: (-3,4) (-3,6) (-5,6) (-7,4)

B: The transformation would be described as a reflection over the y axis

C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width

Step-by-step explanation:

So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)

So using the rule (x, y) → (-x, y) are new points would be:

(-3,4)

(-3,6)

(-5,6)

(-7,4)

This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
