C
There are many ways to see it. First is the dotted and solid lines
The dotted lines mean that it doesn’t include the answer while the dotted line says it does.
When something is greater it’s going to be shaded on top of the line and when something is less it’s going to be shaded below the line

What is 19/25 as decimal

Radda [10]

Well first we need to find how we can turn 25 into 100
Well one way would be to multiply by 4
25 x 4 = 100

Since we multiplied the bottom number by 4 we should multiply the top number by 4.

So..
19 x 4 = 76

So our new fraction is..
76
-----
100

Now we can easily turn this into a decimal.
76/100 = 0.76

Answer = 0.76

Good Luck! :)

find the volume of the cone. either enter exact answer in terms of pi or use 3.14 for pi and round your final answer to the near

SCORPION-xisa [38]

Answer:

$6\pi u^3 = 18.8u^3$

Step-by-step explanation:

the information we have is:

the radius of the circle in the base: $r=3u$ (u for units)

and the height of the cone: $h=2u$

to find the volume we need the formula for the volume of a cone:

$V=\frac{\pi r^2h}{3}$

where r is the radius and h is the height.

Substituting the known values to find the volume:

$V=\frac{\pi (3u)^2(2u)}{3} \\\\V=\frac{\pi (9u^2)(2u)}{3}\\ \\V=\frac{18\pi u^3}{3}\\ \\V=6\pi u^3$

the volume in terms of $\pi$ is $6\pi u^3$

and if we substitute the value of pi: $\pi=3.14$ we get:

$V=6(3.14)u^3\\V=18.8u^3$
