What is the volume of a cylinder, in cubic meters, with a height of 5 meters and a base
diameter of 6 meters? Round to the nearest tenths place.

Answers

Answer 1

Answer:

the answer is 141.3 cubic meters ( if you use 3.14 for pi)

Step-by-step explanation:

the volume equation of a cylinder is

V=  π\(r^{2} h\)

we have to change the 6 meters to 3 meters because the equation for the volume of a cylinder wants the radius not the diameter

V= 3.14 × \(3^{2}\) × 5

that equals 141.3

Answer 2

Answer:

141.4 meters3

Step-by-step explanation:

h\hspace{3px}=\hspace{3px}5\hspace{30px}d\hspace{3px}=\hspace{3px}6

Answer: 30 cubes can be packed.

Step-by-step explanation: The cubes are 1/2 foot each, so 5 can fit in 2 1/2 feet, 3 can fit in 1 1/2 feet, so if you multiply these together, you will get 15, and then when you multiply that by 2 (1 foot) you get 30.

D.12.66
pls help me

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

I believe the answer is D.

Use a number line to order the numbers from least to greatest.

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

26.75 inches

Step-by-step explanation:

First - subtract 31.5 from 85 to get the space for the TV

85 - 31.5 = 53.5

Second - Take the answer from the first step and divide 53.5 by 2

53.5/2 = 26.75

To check:

What is 5/6 of 14 1/2?

PLEASE explain how it is!

please help its last question and i been on it for 15 minutes

Answers

Answer:

5/6 of 14 1/2 is 12.08333333

Step-by-step explanation:

14 1/2 = 14.5

14 = 14

and 1/2 = 0.5

now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6

14.5 ÷ 6 = 2.416666667

and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number

2.416666667 × 5 = 12.08333333

So your answer is 12.08333333

It’s 12 1/12.
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

1. In the first problem, we need to subtract 1 from 9 since there is an addition:

9 – 1 = 8

Next, divide 8 by 2, and we get:

8 ÷ 2 = 4

This means that x = 4

Finally, check the answer by:

2(4) + 1 = 9

2. In the second problem, we need to subtract 3 from 19 since there is an addition:

19 – 3 = 16

Next, divide 16 by 4, and we get:

16 ÷ 4 = 4

This means that x = 4

Finally, check the answer by:

4(4) + 3 = 19

3. In the third problem, we need to add 2 with 7 since there is subtraction:

2 + 7 = 9

Next, divide 9 by 3, and we get:

9 ÷ 3 = 3

This means that x = 3

Finally, check the answer by:

3(3) – 2 = 7

Find the missing sides from the right-angled triangled given below

Answers

Answer:

8 cm

Step-by-step explanation:

\( \large{ \tt{❃ \: STEP - BY - STEP \: EXPLANATION}} : \)

We're provided : In right angled triangle PQR , The length of of PR & length of PQ are 10 cm & 6 cm respectively & we're asked to find out the length of OR.

You need to know : The longest side, which is the opposite side of right angle is the hypotenuse ( h ) . When the reference angle is not given , You can assume the remaining sides either perpendicular ( p ) or base ( b ) .

Here , Hypotenuse ( h ) = 10 cm , Base ( b ) = ? & Perpendicular ( P ) = 6 cm

Before solving, You will have to know : The square of the hypotenuse of a right - angled triangle is equal to the sum of square of the remaining two sides.

\( \large{ \tt{❁ \: LET'S\: START}} : \)

\( \boxed {\large{ \bf {\: ♕ \: {h}^{2} = {p}^{2} + {b}^{2} }}}\)

- Plug the known values and then simplify !

\( \large{ \tt{ ↦ \: {10}^{2} = {6}^{2} + {b}^{2} }}\)

\( \large{ \tt{↦100 = 36 + {b}^{2} }}\)

\( \large{ \tt{↦36 + {b}^{2} = 100 }}\)

\( \large{ \tt{ ↦{b}^{2} = 100 - 36}}\)

\( \large{ \tt{↦ {b}^{2} = 64}}\)

\( \large{ \tt{↦b = \sqrt{64}}} \)

\( \boxed{ \large{ \tt{↦ \: b = 8 \: cm}}}\)

Hence , The length of QR is 8 cm .
