The volume of a box for earrings is 216 cubic centimeters. What is the length of one edge of the box plz help it's due tm
Murrr4er [49]
I’m pretty positive you divide 216 by 4, since that’s the amount of sides a box normally has. The answer would be 54 cubic centimeters. Please let me know if I’m correct, hopefully this helped.

Arisa [49]
The correct answer is choice C. The mean absolute deviation is a way to show the variability, or how spreadout the data is. When the mean absolute deviations are close to each other, that tells us that they're comparable in how they vary. 6.9 is close to 7.1.

Easy way to solve volume of cone
Zinaida [17]
A cone always contain  a right angle.

To solve for the volume of a cone, we need to get the radius of the cone and its height.

Volume of a cone = π r² h/3

radius is the line from the center of the circle of the cone going to the edge of the circle.

height is the measurement of the cone from its pointy tip going downward. 

Assuming the radius of the cone is 3 in. and its height is 6 inches.

Volume of a cone = π * r² * h/3
V = 3.14 * (3in)² * 6in/3
V = 3.14 * 9in² * 2in
V = 56.52 in³

Diana put $8000 in a 10-year CDpaying 5% interest compoundedmonthly. After 2 years, shewithdrew all her money, and as anearly wi
Svet_ta [14]

Answer:

$8,430.23

Explanation:

From the statement of the problem:

• The principal amount = $8,000

,

• Interest Rate = 5%

,

• Compounding Period = 12 (Monthly)

The compound interest formula is given as:

A(n)=P\left(1+\frac{r}{k}\right)^{nk}

Using the compound period formula, we first, calculate the amount in her account at the end of 1 year.

\begin{gathered} A(1)=8000\left(1+\frac{0.05}{12}\right)^{12\times1} \\ A(1)=\$8409.30 \end{gathered}

This means that the interest she made during the first year is:

\text{ Interest during the first year}=8409.30-8000=\$409.30

Next, calculate the amount in her account at the end of the second year.

\begin{gathered} A(2)=8000\left(1+\frac{0.05}{12}\right)^{12\times2} \\ A(2)=\$8839.53 \end{gathered}

Since she paid back all the interest she made during the first year, the amount Diana was left with is:

\begin{gathered} 8839.53-409.30 \\ =8,430.23 \end{gathered}

Diana was left with $8,430.23.
