There are two right circular cylinders. The radius of the first cylinder is 4 centimeters, and its height is 5 centimeters. The radius of the second cylinder is 12 centimeters, and its height is also 5 centimeters. What is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? A. 3:1 B. 5:1 C. 6:1 D. 9:1

Answers

Answer 1

Answer:

D. 9:1

Step-by-step explanation:

The formula for the volume of a cylinder is πr² · h (pi · radius² · height) (use 3.14 for pi).

The two right circular cylinders have the same height. The larger cylinder has a radius that is three times the size of the smaller radius.

4 · 3 = 12

However, in the equation for volume, the radius is squared. Because of this, the larger cylinder is 9 times the size of the smaller cylinder because 3² = 9.

You can check your work by finding the volume of the two cylinders using the volume formula πr² · h:

3.14 · 4² · 5 = 251.2

3.14 · 12² · 5 = 2,260.8

The cylinder with a radius of 12 cm is 9 times the size of the cylinder with a radius of 4 cm.

2.260.8 ÷ 9 = 251.2

252.1

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.

Answers

9514 1404 393

Answer:

  2463.01 mm²

  2461.76 mm² if you use 3.14 for π

Step-by-step explanation:

The formula for the area of a circle is ...

  A = πr²

where r is the radius, half the diameter.

For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...

  A = π(28 mm)² = 784π mm²

For an appropriate value of π, the area is ...

  784π mm² = 2463.00864... mm² ≈ 2463.01 mm²

For 3.14 as the value of π, the area is ...

  784(3.14) mm² = 2461.76 mm²

_____

Comment on pi

Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the number r of rides you can ride.

Answers

Answer:

4 rides

Step-by-step explanation:

Total amount = $21.50

Entry charge = $20.50

Amount left = $21.50 - 20.50 = $1

Number of rides

\(r = \frac{1}{0.25} = \frac{100}{25} = 4 \\ \)

Another way:

\( 0.25\:r + 20.50 = 21.50\\

0.25\:r = 21.50 - 20.50\\

0.25\:r = 1\\

r = \frac{1}{0.25}\\

r = \frac{100}{25}\\

r = 4\\\)

The second sentence. They told you that 5 bottles EACH contains 1/2 liter of water. That means that 1 bottle = 1/2 liter of water. In order to find the total amount, you need to do 5 x 1/2, which is literally what the questions asks for. Only the second question contains what they ask for. Hope this helped! :D

The situations that can be represented by 1/2 x 5 are given below.

Options A, B, and D are the correct answer.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Diego lives 5 miles from school.

Elena lives 1/2 as far away as Diego.

The distance Elena lives from the school.

= 1/2 x 5

Number of bottles = 5

Each bottle contains 1/2 liter of water.

The total liters of water in 5 bottles.

= 1/2 x 5

Noah has 5 meters of rope.

Length of each rope = 1/2 meter

The number of ropes of 1/2 meter.

= 5/(1/2)

= 10

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answers

Answer:

The smallest value the expression could have is 1.

Step-by-step explanation:

If a and b are different numbers selected from the first 25 whole numbers (1 through 25), and a is greater than b, the smallest value the expression could have is when b is the smallest possible value and a is the next smallest value.

The smallest possible value for b is 1, and a must be greater than b. Therefore, the smallest possible value for a is 2.

So, the smallest value the expression could have is 2 - 1 = 1.

The smallest value the expression could have is 2-1=1
