nlexa [21]

Answer:

The answer in the procedure

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

$V=\pi r^{2} h$

we have

$r=10\ cm$

$h=9\ cm$

substitute

$V=\pi (10)^{2}(9)=900\pi\ cm^{2}$

step 2

Find the volume of the cone

The volume of the cone is equal to

$V=(1/3)\pi r^{2} h$

we have

$r=10\ cm$

$h=9\ cm$

substitute

$V=(1/3)\pi (10)^{2}(9)=300\pi\ cm^{2}$

therefore

we have

$Vcylinder=900\pi\ cm^{2}$

$Vcone=300\pi\ cm^{2}$

$Vcylinder=3Vcone$

What's this question?? I can't figure it out

yKpoI14uk [10]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

We can see that the denominators are not the same. You cannot do that when adding or subtracting fractions.

So you must LCD (Least common denominator)

Multiply the denominators to get LCD:

$5 * 10 = 50$

So our denominators are 50.

Now we do crisscross multiplication:

$\frac{4 * 10}{50} - \frac{3 * 5}{50}$

$\frac{40}{50} - \frac{15}{50}$

$\frac{25}{50}$

Simplify:

$\frac{25 / 2}{50 / 2}$

$\frac{1}{2}$
