Answer :
Sure! Let's solve each of these questions step-by-step:
Question 11:
To find the volume of a cylinder, the formula is:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
Given a radius of 5 and a height of 3, the volume can be calculated as:
[tex]\[ \text{Volume} = \pi \times 5^2 \times 3 = \pi \times 25 \times 3 = 75\pi \][/tex]
The correct answer is D. [tex]\(75\pi\)[/tex].
Question 12:
Again, using the formula for the volume of a cylinder:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
The diameter is given as 10, so the radius is 5 (since radius is half of the diameter). The height is 25.
[tex]\[ \text{Volume} = \pi \times 5^2 \times 25 = \pi \times 25 \times 25 = 625\pi \][/tex]
The correct answer is B. [tex]\(625\pi\)[/tex].
Question 13:
We need to find which option is NOT equal to the others. Let's look at the options:
- A. [tex]\(1 \text{ lb} = 16 \text{ oz}\)[/tex]
- C. [tex]\(16 \text{ oz} = 16 \text{ oz}\)[/tex]
- B. [tex]\(\frac{1}{4} \text{ gallon}\)[/tex] is not equal to 16 oz. Since 1 gallon = 128 oz, [tex]\(\frac{1}{4}\)[/tex] gallon is 32 oz.
- D. [tex]\(\frac{1}{2000} \text{ short ton} = 16 \text{ oz}\)[/tex] (since a short ton is 2000 lbs or 32000 oz).
Option B ([tex]\(\frac{1}{4} \text{ gallon} = 32 \text{ oz}\)[/tex]) is not equal.
The correct answer is B.
Question 14:
1 gallon equals 4 quarts. So, for 8 gallons:
[tex]\[ 8 \times 4 = 32 \text{ quarts} \][/tex]
The correct answer is not listed because it should be 32.
Question 15:
Using the formula for the volume of a cylinder:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
The diameter is 6, so the radius is 3. Height is given as 10.
[tex]\[ \text{Volume} = \pi \times 3^2 \times 10 = \pi \times 9 \times 10 = 90\pi \][/tex]
The correct answer is D. [tex]\(90\pi\)[/tex].
Question 16:
Given a base area and volume, to find the height use:
[tex]\[ \text{Volume} = \text{base area} \times \text{height} \][/tex]
Solving for height:
[tex]\[ \text{height} = \frac{\text{Volume}}{\text{base area}} = \frac{250\pi}{25\pi} = 10 \][/tex]
The correct answer is B. 10 units.
Question 17:
A unit used to measure volume is one that represents a three-dimensional space. The options are:
- A. liter (volume unit)
- B. cubic meter (volume unit)
- C. quart (volume unit)
- D. square meter (area unit)
Square meter is not a volume unit.
The correct answer is D. square meter.
Question 18:
Given the volume and height of a cylinder, we need to find the radius. The formula for volume:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
Solving for the radius:
[tex]\[ 250\pi = \pi \times \text{radius}^2 \times 10 \][/tex]
Divide by [tex]\(\pi \times 10\)[/tex]:
[tex]\[ \text{radius}^2 = 25 \][/tex]
[tex]\[ \text{radius} = \sqrt{25} = 5 \][/tex]
The correct answer is A. 5 cm.
Question 19:
Without more details about containers A and B, such as their dimensions or capacities, we can't decide which holds more water.
The correct answer is D. There is not enough information given.
Question 20:
For the volume of a pyramid, the formula is:
[tex]\[ \text{Volume} = \frac{1}{3} \times \text{base area} \times \text{height} \][/tex]
Without the base area given, the volume can't be determined.
The volume can't be accurately calculated with the information provided.
