Volume answer rn djdjd
Answer:
133.7π cm^3 or approximately 418.77430072 cm^3.
Step-by-step explanation:
For the cylinder half, use the formula: π*r^2*h, or pi times radius squared times height.
Since the diameter is 8, which means the radius is 4, and the height is 6, the volume of the cylinder would be 96π or 301.59289474...
For the cone on top, use the formula 1/3 (π*r^2*h), or one third pi times radius squared times height. Don't forget to calcuate the part in parentheses before dividing it by three.
Because the overall height was 13, you can subtract the 6 from the cylinder to get the cone's height. It has a height of 7 and a radius of 4 just like the cylinder. The volume of the cone is 112π/3 or 37.3π.
Now add both volumes together to get 133.7π cm^3 or approximately 418.77430072 cm^3.

Answer:
The sign of each y-coordinate changed.
Step-by-step explanation:
This was a reflection over the x-axis.
If you look at point F, it is (-5, -1) the corresponding point F' is (-5,1). Notice the numerical values of x and y are the same, but the sign of y flipped from negative to positive. The other four points all follow the same pattern.

Which of the following pairs of coordinates represents the same point in polar coordinates? Check all that apply.
(r,theta) and (r,theta+2pi)
(r,theta) and (-r,theta)
(r,theta) and (-r,theta+ 2pi)
(r,theta) and (-r,theta+pi)
A point that has the polar coordinate [tex](r,\theta)[/tex] can also be represented by [tex](r, \theta+2n\pi)[/tex] and [tex](-r, \theta+(2n+1)\pi)[/tex].
From the list of given options, [tex](r,\theta)[/tex] and [tex](-r, \theta+\pi)[/tex] are represents the same point
Recall that:
[tex](r, \theta+2n\pi)[/tex] and [tex](-r, \theta+(2n+1)\pi)[/tex] represents the same point
Where n is an integer
Assume [tex]n = 0[/tex]
[tex](r, \theta+2n\pi)[/tex] becomes
[tex](r, \theta+2n\pi) = (r, \theta+2\times 0 \times \pi)[/tex]
[tex](r, \theta+2n\pi) = (r, \theta+0)[/tex]
[tex](r, \theta+2n\pi) = (r, \theta)[/tex]
Similarly,
[tex](-r, \theta+(2n+1)\pi)[/tex] becomes
[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(2\times 0+1)\pi)[/tex]
[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(0+1)\pi)[/tex]
[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+(1)\pi)[/tex]
[tex](-r, \theta+(2n+1)\pi)=(-r, \theta+\pi)[/tex]
This means that: [tex](r,\theta)[/tex] and [tex](-r, \theta+\pi)[/tex] represent the same point.
Hence, (d) is correct.

Not sure how to do this.
Answer:
200π
Step-by-step explanation:
Surface area is abbreviated to SA
TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π
What is the volume of a sphere with a radius of 3.1 cm, rounded to the nearest tenth
of a cubic centimeter?
image below look at it and please help
Answer:
AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm

Suppose that 50% of the watches produced by a certain factory are defective. A store buys a box with 400 watches produced by this factory. Assume That this is a random sample.(a) Write an expression for the exact probability that at least 215 watches out ofthe 400 are defective. You do not need to numerically evaluate it.(b) Argue whether the normal or the Poisson approximation is appropriate to es-timate the above probability and then estimate it.
Answer:
[tex](a)\ P(x \ge 215)[/tex]
[tex](b)\ P(x \ge 214.5) = 0.07353[/tex]
Step-by-step explanation:
Given
[tex]p = 0.50[/tex] ---- proportion of watches with defects
[tex]n = 400[/tex] --- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means: [tex]\ge[/tex]
So, the probability is represented as: [tex]P(x \ge 215)[/tex]
Solving (b): Calculate [tex]P(x \ge 215)[/tex]
Normal or Poisson: Normal distribution is characterized by 2 parameters [tex]\mu[/tex] and [tex]\sigma[/tex].
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
[tex]\mu =np[/tex]
[tex]\mu = 0.50 * 400[/tex]
[tex]\mu = 200[/tex]
Calculate standard deviation
[tex]\sigma = \sqrt{\mu (1 - p)[/tex]
[tex]\sigma = \sqrt{200 * (1 - 0.50)[/tex]
[tex]\sigma = \sqrt{200 * 0.50[/tex]
[tex]\sigma = \sqrt{100[/tex]
[tex]\sigma = 10[/tex]
By continuity correction, we have:
[tex]x \to x - 0.5[/tex]
[tex]x \to 215 - 0.5[/tex]
[tex]x \to 214.5[/tex]
So, we have:
[tex]P(x \ge 215) = P(x \ge 214.5)[/tex]
Calculating [tex]P(x \ge 214.5)[/tex], we have:
[tex]P(x \ge 214.5) = 1 - P(x < z)[/tex]
Calculate z score
[tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]z = \frac{214.5 - 200}{10}[/tex]
[tex]z = \frac{14.5}{10}[/tex]
[tex]z = 1.45[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - P(x < 1.45)[/tex]
Using the z score probability table, we have:
[tex]P(x < 1.45) = 0.92647[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - 0.92647[/tex]
[tex]P(x \ge 214.5) = 0.07353[/tex]

Sara has 3 1/2 feet of ribbon.
She needs 2/3 foot to make one bow.
How many bows can she make?
Answer:
5 bows
Step-by-step explanation:
Total feets of ribbon = 3 1/2
Fraction required to make a bow = 2/3
Number of bows that can be made = (total ribbon / Fraction required to make a bow)
3 1/2 ÷ 2/3
7/2 ÷ 2/3
7/2 * 3/2
= 21 / 4
= 5.25
