Item 16 A sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. What is the difference of the vol

Zigmanuir [339]

Answer:

$672\pi \text{ cm}^3$ .

Step-by-step explanation:

We have been given that a sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. We are asked to find the difference of the volumes of the spheres.

We will use volume formula of sphere to solve our given problem.

$\text{Volume of sphere}=\frac{4}{3}\pi r^3$ , where r is radius of sphere.

The difference of volumes would be volume of larger sphere minus volume of smaller sphere.

$\text{Difference of volumes}=\frac{4}{3}\pi(\text{8 cm})^3-\frac{4}{3}\pi(\text{2 cm})^3$

$\text{Difference of volumes}=\frac{4}{3}\pi(512)\text{ cm}^3-\frac{4}{3}\pi(8)\text{ cm}^3$

$\text{Difference of volumes}=\frac{4}{3}\pi(512-8)\text{ cm}^3$

$\text{Difference of volumes}=4\pi(168)\text{ cm}^3$

$\text{Difference of volumes}=672\pi\text{ cm}^3$

Therefore, the difference between volumes of the spheres is $672\pi \text{ cm}^3$ .

Math question.......................................

ValentinkaMS [17]

Question 1:

The answer is A: Sam.

His table is the only one that follows the conditions set in the question.

Question 2:

Choosing two points; (0, 14) and (4, 10)

Slope (m) = $\frac{10 - 14}{4 - 0} = \frac{-4}{4}$ = -1

Thus, equation,

$y - y_{1} = m(x - x_{1})$

$y - 10 = -1(x - 4)$

$y = -x + 14$

I'm getting that for my equation of the line, so my best guess is that the answer is C.

The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.

The answer is C. ( I believe )

Answer:

$13.00

Step-by-step explanation:

so you multiply $5.50 by 2.25 gallons

5.50

x 2.25 =

2750+1100+1100= 12.3750

then you round it off which will make your answer $12.38

then to find out how much it will be with the taxes you add $12.38 and .072 to it to make the total for the ice cream $13.00

Sati [7]

<u>ANSWER: </u>

Scott has 6000 points in his fantasy baseball league.

<u>SOLUTION: </u>

Given, Donal currently has 7,200 points in his fantasy baseball league.

It is 20% more points than Scott points.

We need to know how many points does scott have?

Let the points with scott be x.

Then, according to give information

Donal points = scott points + 20% of scott points

$\begin{array}{l}{7200=x+20 \% \times x} \\\\ {7200=x+\frac{20}{100} \times x} \\\\ {7200=x+\frac{1}{5} \times x} \\\\ {7200=x+\frac{x}{5}}\end{array}$

By multiplying with 5 on both sides, we get

$\begin{array}{l}{7200 \times 5=5 \times x+x} \\\\ {36000=5 x+x} \\\\ {6 x=36000} \\\\{x=\frac{36000}{6}} \\\\ {x=6000}\end{array}$

Hence, scott has 6000 points in his fantasy baseball league.
