zhenek [66]

Answer:

13 Kilometers = 13000 meters

Step-by-step explanation:

Using the conversion:

1 kilometers = 1000 m

We can find how much meters are in 13 km.

=> 13 Kilometers = 1000 x 13

=> 13 Kilometers = 13000 meters

Therefore, in 13 kilometers, there is 13000 meters.

The radius of the large sphere is double the radius of the small sphere. How many times does the volume of the large sphere than

pshichka [43]

Answer:

8 times larger.

Step-by-step explanation:

The radius of the large sphere is double the radius of the small sphere.

Question asked:

How many times does the volume of the large sphere than the small sphere

Solution:

<u>Let radius of the small sphere = </u> $x$ <u />

<u>As the radius of the large sphere is double the radius of the small sphere:</u>

Then, radius of the large sphere = $2x$

To find that how many times is the volume of the large sphere than the small sphere, we will <em><u>divide the volume of large sphere by volume of small sphere:-</u></em>

For smaller sphere: $Radius = x$

$Volume \ of \ sphere = \frac{4}{3} \pi r^{3}$

$=\frac{4}{3} \pi x^{3}$

For larger sphere: $Radius = 2x$

$Volume \ of \ sphere = \frac{4}{3} \pi r^{3}$

$=\frac{4}{3} \pi (2x)^{3}$

Now, we will divide volume of the larger by the smaller one:

$=\frac{4}{3} \pi (2x)^{3}\div\frac{4}{3} \times\frac{\pi }{1 } \times x^{3}\\ \\ =\frac{4}{3} \pi\times8x^{3} \times\frac{3}{4\pi }\ \times\frac{1}{x^{3} }$

$\frac{4}{3}\pi\ is \ canceled\ by\ \frac{3}{4\pi } \ and\ also\ x^{3} is\ canceled\ by \ \frac{1}{x^{3} }$

<u>Now, we have</u>

= $\frac{8}{1}$

Therefore, the volume of the large sphere is 8 times larger than the smaller sphere.
