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

Answer:

16 bags

Step-by-step explanation:

To find this, we divide 2 over 1/8, to see how many units of 1/8 fits into that of 2.

$\frac{2}{\frac{1}{8} }$ can be rewritten as 2*8. 2*8 = 16 bags.

How do i know when a graph is continuous or discrete?

Karo-lina-s [1.5K]

When looking at a graph, discrete data will have all the pints connected so it will look something like the 1st picture that I provided. Something that is discrete can not be broken down into decimals or fractions so we usually say discrete things can be counted.

On the other hand, continuous data is usually things that we associate with measuring. These types of graph will have dots all over them and they can have fractions and decimals in them.
