Volume of Cylinders, Cones, and Spheres
I NEED HELP ASAP!!
Answer:
8) 144pi
9) 196pi
11) 18pi
12) 298.67pi
Step-by-step explanation:
CylindersThe volume of a cylinder is [tex]V = \pi r^{2} h[/tex], where r represents the radius of the base and h represents the height.
For the first cylinder, the radius of the base is 4 and the height is 9.
[tex]V = \pi (4)^{2} (9)\\V = \pi(16)(9)\\V = 144\pi[/tex]
For the second cylinder, the diameter is 6 and the height is 2. Since the radius is half the diameter, the radius is 3.
[tex]V = \pi (3)^{2} (2)\\V = \pi(9)(2)\\V = 18\pi[/tex]
SphereThe volume of a sphere is [tex]V = 4\pi r^{2}[/tex], where r is the radius of the sphere.
The diameter is 14, meaning the radius must be 7.
[tex]V = 4\pi (7)^{2} \\V = 4\pi (49)\\V = 196\pi[/tex]
ConeThe volume of a cone is [tex]V = \pi r^{2} (h/3)[/tex], where r is the radius and h is the height.
The radius is 8, and the height is 14.
[tex]V = \pi (8)^{2} (14/3)\\V = \pi (64) (14/3)\\V = \frac{896}{3} \pi\\V = 298.67\pi[/tex]
5.
The height of a cylinder is 6 Inches. The radius of the base is 8 inches.
Which expression can be used to approximate the volume of the cylinder?
A
2 x 8 x 3.14 6
B
4x3.146
с 82 3.146
D 42 x 3.146
the volume of cylinder is 3.14 r^2×h
Answer: c

Your ship sinks and you swim to a nearby island. On this island, the inhabitants do not use money. The island residents use island fruit as money.
If 60 bananas = 20 coconuts
35 figs = 15 oranges
10 coconuts = 25 figs
200 figs = 1 boat
How many bananas would you need to purchase a boat to get off the island?
Answer:
240 bananas
Step-by-step explanation:
You would need 8 sets of figs. 10 coconuts is equal to 25 figs so you need 80 coconuts. You would need enough bananas to get 4 sets of coconuts. 60*4 = 240
Answer:
To buy the boat you would need 240 bananas.
Explanation:
3 bananas = 1 coconut
1 coconut = 2.5 figs
200 figs (price of boat) = 80 coconuts
80 coconuts (price of boat) = 240 bananas

What is the value of x? Show me how you got that answer.
Answer:
x = 3
Step-by-step explanation:
The angle measuring 5x and the angle measuring 165° are a linear pair, so they are supplementary. Their measures add to 180°.
5x + 165 = 180
5x = 15
x = 3
The present price of a motorcycle is
Rs. 2,25,000. If its price is depreciated per year by 8 %, after
how many years will be the price of the motorcycle be
Rs. 1,75,204.80 ? Find it.
Answer:
3.25 years
Step-by-step explanation:
The computation of the number of years is shown below:
Given that
PV = $225,000
RATE = 8%
PMT = $0
FV = $175,204.80
The formula is shown below:
= NPER(RATE;PMT;PV;FV;TYPE)
After applying the above formula, the number of years would be 3.25 years
The same would be considered

A local school board wants to determine if the proportion of households in the district that would support starting the school year a week earlier has changed from the previous year. Last year, the school board determined that 65% of households supported starting school earlier. They ask a random sample of 100 households this year, and 70% state they would support starting the school year earlier. Which hypotheses would determine if the proportion of households that support starting school earlier has changed this year?
Group of answer choices
H 0: p not-equals 0.70, H alpha: p = 0.70
H 0: p = 0.70, H alpha: p not-equals 0.70
H 0: p = 0.65, H alpha: p greater-than 0.65
H 0: p = 0.65, H alpha: p not-equals 0.65
Answer:
C
Step-by-step explanation:
Considering the situation, the hypotheses set that would determine if the proportion of households that support starting school earlier has changed this year is given by:
[tex]H_0: p = 0.65, H_\alpha: p \neq 0.65[/tex]
What are the hypotheses tested?At the null hypotheses, it is tested if there has been no change, that is, the proportion is still of 0.65 = 65%, hence:
[tex]H_0: p = 0.65[/tex]
At the alternative hypotheses, it is tested if there has been a change, that is, the proportion is not of 0.65 = 65% anymore, hence:
[tex]H_\alpha: p \neq 0.65[/tex]

In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?
A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s
Answer:
C: 31 m/s
Step-by-step explanation:
It falls from a dam.
Thus;
Initial velocity; u = 0 m/s
Height; h = 49 m
Acceleration due to gravity is 9.8 m/s²
To solve for the final velocity this, we will use Newton's third equation of motion;
v² = u² + 2gh
v² = 0² + 2(9.8 × 49)
v = √960.5
v ≈ 31 m/s

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
25%
33%
57%
75%
Answer:
25%
Step-by-step explanation:
An easy way to figure this out is just by dividing the initial amount of students (18) by the current amount of students (24), and then subtracting 1.
So, 18/24 = 0.75 (aka 75%), and 1 - 0.75 = 0.25 (aka 25%)
