Given:
A composite figure consisting of a cylinder with radius r and height h and a half-sphere with a radius r.
To find:
The total volume of the composite figure.
Solution:
To determine the total volume of the figure, we add the volume of the cylinder and the volume of the half-sphere.
The volume of a cylinder, [tex]V= \pi r^{2} h.[/tex]
The given cylinder has a radius of 3.9 units and a height of 4.3 units. Assume π equals 3.14.
The volume of the cylinder, [tex]V = (3.14)(3.9^{2} )(4.3)= 205.36542[/tex] cubic units.
The volume of a half-sphere, [tex]V= \frac{2}{3} \pi r^{3} .[/tex]
The given half-sphere has a radius of 3.9 units, assume π equals 3.14.
The volume of the half-sphere, [tex]V= \frac{2}{3} (3.14)(3.9^{3} ) = 124.17444[/tex] cubic units.
The total volume of the composite figure [tex]= 205.36542+124.17444=329.53986[/tex] cubic units.
Rounding this off to the nearest hundredth, we get the volume of the cone as 329.54 cubic units.

Answer:
angle A = 166 degrees
Step-by-step explanation:
so first you have to look at the problem and see what type of relationship the angles have. so if you draw it out yourself, it makes it a little easier and you can see that the two angles are corresponding angles, which means theyre both congruent or, equal.
after you find that out you can set up an equation so,
7x + 40 = 3x + 112
you do the math...
4x + 40 = 112
4x = 72
x = 18
but you cant stop here, you have to plug in x to find teh entire angle A
7 (18) + 40 = ?
126 + 40

Answer:
(x + 2)(x - 7)
Step-by-step explanation:
Given
x² - 5x - 14
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

2 × - 7 = - 14 and 2 - 7 = - 5, thus
x² - 5x - 14 = (x + 2)(x - 7)
Tammy is buying a soft toy from a shop. The cost of the toy is 9 dollars and she also has to pay a sales tax that is 15% of the price of the toy. She wants to know the total cost she will have to pay.
Answer:10.35 dollars
Step-by-step explanation: 15% of 9 dollars is 1.35
so you add 1.35 to 9 dollars to find the total cost
The total cost she will have to pay for the toy is $10.35.
What is the percentage?A percentage is a figure or ratio that can be stated as a fraction of 100. If we need to calculate the percentage of a number, we must divide it by its full value and then multiply it by 100. As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".
Given the cost of the toy = $9
sale tax on toy = 15% of the total price
sale tax on toy = 15% of 9
sale tax on toy = 0.15 x 9
sale tax on toy = $1.35
total cost to pay = $9 + $1.35
total cost to pay = $10.35
Hence total cost to pay is $10.35.

1. The values in the x-axis increase by 2 hence a=3-2=1 and c=7+2=9. For the y-values, they increase by 1.
2. The equation of the line can be written in the slope form of y=mx+c where m is the gradient of the line and c is the y-intercept
Taking points on the line ; (-2,-2) and (2,0) the gradient m is ;

Find the radius circumference =62.8mi
Answer:
r = 10
Step-by-step explanation:
C = 62.8 = 2π·r
62.8 = 2·3.14·r
r = 62.8/2·3.14
= 31.4/3.14
= 10
Answer:
10 miles
Step-by-step explanation:
The circumference of a circle can be found using:
[tex]c=2r\pi[/tex]
We know circumference is 62.8, so we can substitute it in
62.8=[tex]2r\pi[/tex]
We want to find r, so we have to isolate it.
Divide both sides by [tex]2\pi[/tex] or 2*3.14 which is 6.28
62.8=[tex]2r\pi[/tex]
62.8=6.28r
62.8/6.28=6.28r/6.28
r=10
So, the radius is 10 miles
PLS HELP! THIS IS OVERDUE! ''What is the range of possible lengths for the third side of a triangle that has side lengths of 7 and 10?''
The length has to be greater than the absolute difference between the other two lengths, but less than the sum of them. In other words, if your unknown side length is a, and the other two are b and c, then its |b - c| < a < b + c
So, putting in your values, you have 10 - 7 < a < 10 + 7, which is 3 < a < 17
So, your range is from 3 to 17 (non inclusive).
The length has to be greater than the difference between the named two lengths, but less than the sum of them. So 3-17 is your answer.

a(1 ) = -2 a(n) = a(n - 1) - 5 Find the 4 ^ (th) term in the sequence .
Answer:
-17
Step-by-step explanation:
Each term in the sequence is 5 less than the one before, so the first 4 terms are ...
-2, -7, -12, -17
The 4th term of the sequence is -17.
__
The general term (an) of the sequence can be written as ...
an = a1 +d(n -1)
where a1 is the first term and d is the common difference. Here, those are ...
a1 = -2, d = -5
so the general term is ...
an = -2 -5(n -1)
We can use this to find the 4th term:
a4 = -2 -5(4 -3)
a4 = -17

Use a trigonometric ratio to find the value of x. Round your answer to the nearest
tenth.
Answer:
x = 7.6
Step-by-step explanation:
Label the values you have on the triangle: The X is opposite, the 33 is your theta (ø) and 14 is your hypotenuse
Plug these values into the equation sin(ø)=o/h making the equation sin(33)=x/14.
Take the 14 and multiply it on the opposite side, making the equation look like this: 14xsin(33)=x
Then plug this into the TI-83/84 calculator and make sure it is degree mode (mode, degree)
Then just round to the nearest tenth. :)
