Step-by-step explanation:

The radius <em>r</em> is 5 in (r = D/2). so the volume <em>V</em><em> </em>of the beach ball is

V= \dfrac{4 \pi}{3}r^3 = \dfrac{4 \pi}{3}(5\:\text{in})^3

\:\:\:\:\:= 523.6\:\text{in}^3

Are these ratios equivalent?
Debora [2.8K]
<h3>Answer:  Yes</h3>

========================================================

Explanation

The ratio 8:10 simplifies to 4:5 when you divide both parts by 2.

The ratio 16:20 simplifies to 4:5 when you divide both parts by 4

Therefore the two ratios 8:10 and 16:20 are both equal 4:5, so they are equal to one another.

------------

Put another way,

(8 large)/(10 small) = (16 large)/(20 small)

8/10 = 16/20

8*20 = 10*16 ... cross multiply

160 = 160

We get a true equation, so the first equation is true as well.

This shows the ratios are equivalent.

-------------

Or you could have...

(8 large)/(16 large) = (10 small)/(20 small)

8/16 = 10/20

8*20 = 16*10

160 = 160

We get the same conclusion as before.

shtirl [24]

Given:

\dfrac{2}{10} divded by \dfrac{2}{4}.

To find:

The solution for the given division problem.

Solution:

We have, \dfrac{2}{10} divded by \dfrac{2}{4}. It can be written as

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}

Therefore, the solution for the given division problem is \dfrac{2}{5}.
