A cylinder has a height of 13 millimeters and a radius of 8 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.

Answers

The volume of the cylinder is 9,184.5 cubic millimeters.

Ok so to answer this question we have to apply the next formula:
Volume of a cylinder (V) : π x radius ² x height
Replacing with the values given and solving for v (Volume)
V = 3.14 x 15² x 13
V = 9,184.5 mm3
In conclusion, the volume of the cylinder is 9,184.5 cubic millimeters.

What is 5x - 43 plz I can’t find out what it is

Answers

Answer:

x = 8.6

Simplifying

5x + -43 = 0

Reorder the terms:

-43 + 5x = 0

Solving

-43 + 5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '43' to each side of the equation.

-43 + 43 + 5x = 0 + 43

Combine like terms: -43 + 43 = 0

0 + 5x = 0 + 43

5x = 0 + 43

Combine like terms: 0 + 43 = 43

5x = 43

Divide each side by '5'.

x = 8.6

Simplifying

x = 8.6

Step-by-step explanation:

Hope it is helpful...

x = 8.6
43 divided by 5 = 8.6

Which Ratios are equivalent to 24:4? Choose ALL the equivalent ratios

Answers

Answer:

6:1 and 12:2. cuz if u multiply each, you will eventually get 24:4

Step-by-step explanation:

If the result of the two ratios are same, then they are said to be equivalent ratio.

The ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.

What is equivalent ratio?

Equivalent ratio is the ratio which is same in the value as the original ratio but the numerator and denominator is different for both the ratios.

Given information-

The ratio given in the problem is,

[tex]24:4[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{24}{4}\\[/tex]

Simplify it,

[tex]r=\dfrac{6}{1}[/tex]

[tex]r=6:1[/tex]

Check all the options which is equivalent to the ratio 6:1.

A) The ratio given in the option A is

[tex]6:1[/tex]

Which is equal tot he given ratio. Thus the option A is correct option.

B) The ratio given in the option B is

[tex]8:4[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{8}{4}\\[/tex]

Simplify it,

[tex]r=\dfrac{2}{1}[/tex]

[tex]r=2:1[/tex]

Which is not equal to the given ratio. Thus the option B is incorrect option.

C)The ratio given in the option C is

[tex]12:2[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{12}{2}\\[/tex]

Simplify it,

[tex]r=\dfrac{6}{1}[/tex]

[tex]r=6:1[/tex]

Which is equal to the given ratio. Thus the option C is correct option.

D) The ratio given in the option D is

[tex]15:3[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{15}{3}\\[/tex]

Simplify it,

[tex]r=\dfrac{5}{1}[/tex]

[tex]r=5:1[/tex]

Which is not equal to the given ratio. Thus the option D incorrect option.

Hence the ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.
