What is the volume of the composite figure shown? Use 3.14 for π.

Answers

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

The answer to this question is 25.12

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1

Answers

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

_______ km


I GIVE BRAINLIEST TO THE FIRST CORRECT ANSWER!!

Answers

Answer:

[tex]57\:\mathrm{km}[/tex]

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let [tex]x[/tex] represent how much farther his truck can go, in kilometers:

[tex]\frac{2}{76}=\frac{1.5}{x}[/tex]

Cross-multiplying, we get:

[tex]2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}[/tex]

Answer:

Step-by-step explanation:

2 ÷ 76 = 1.5 ÷ d

2d = 76 × 1.5

d = 57 km
