Answer:
Below.
Step-by-step explanation:
To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.
The total volume = 1/2 * 4/3 π (15)^3 + π (15)^2 * 85
= 67151.5 ft^3.
Step-by-step explanation:
find the volume of a sphere with a radius of 15 ft and divide by 2 (because there is only half a sphere on top of the silo).
then add the volume of a cylinder with a radius of 15 ft and a height of 85 ft (because we need to deduct the radius of the sphere from the total height to get the height of the cylinder itself).

What is the volume of the rectangular prism below in cubic inches?
Answer:
24
Step-by-step explanation:
The volume formula is all the dimensions multiplied together, or lengthxwidthxheight.
So, you do 1x1x2 which is 2 feet. HOWEVER, it is looking for CUBIC INCHES, not cubic FEET.
There are twelve inches in a foot so 2x12=24 inches.

Amy fills an ice cream cone to the top edge. The diameter of the ice cream cone is 2 inches and its height is 6 inches. Don fills a bowl (V = 5 cubic inches) with ice cream. Amy has how much more ice cream than Don?
Answer:
1.28 in³
Step-by-step explanation:
Volume of Amy's cone
Cone = 1/3πr²hCone = 1/3 x 3.14 x 1² x 6Cone = 2 x 3.14 = 6.28 in³Volume of Don's bowl
It's given to be 5 in³Difference
Amy's cone - Don's bowl6.28 - 51.28 in³Answer:
So obviously in the context of this question you are meant to find the volume. Since Don's bowl already has a given value of 5 cubic inches we will use that same unit when calculating amy's ice cream cone volume.
Step-by-step explanation:
You are given that amy has a cone and need to find the volume. The formula for the volume of a cone is (V=πr^2*h/3).
π = pi or 3.14......
r = radius (in this case the opening/ diameter of the ice cream cone is given as 2 inches and the radius is half of diameter so d/2 = r (r=1)
h = height (in this case it is given that height is 6 inches)
Remember all variable units must be kept the same so in this case all units are inches.
Now Plug in and solve V = [tex]3.14*(1)^{2} *\frac{(6)}{3}[/tex]
Remember order of operations / PEMDAS (in this case, do exponent first then just multiply from left to right and at the end divide that number by 3.
V= 6.28 cubic inches (since all our units were inches and we are finding cubic volume of a cone)
Now Amy volume of cone - Don volume of bowl = your answer. 6.28-5 = 1.28 cubic inches

The slope of line that passes through the points (1, -6) and (-2, –8) is 2/3.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
y = mx + b
In which the coefficients are described as follows:
• The coefficient m is the slope of the function, representing the rate of change of the function.
• The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).
Here the points are(1, -6) and (-2, –8) :
and it is to find the equation of line passing through these points :
Now using slope formula to find the slope of line m :
m = (y₂-y₁)/ (x₂-x₁)
m = (-8+6)/(-2-1)
m = -2/-3
m = 2/3
Therefore, the slope of line that passes through the points (1, -6) and (-2, –8) is 2/3.

Please help with both precalc questions! 2 dif problems
Answer:
Step-by-step explanation:
For the first problem you have:
[tex]sin^2(x)-sin(x)=0[/tex]
Factor out a sin(x) to get:
[tex]sin(x)[2sin(x)-1]=0[/tex]
Individually, set both terms equal to zero:
[tex]sin(x)=0[/tex]
[tex]2sin(x)-1-0[/tex]
The first equation is asking "sine of what angle gives zero?" The sine of 0 will give zero, and so will the sine of pi, and 2pi, etc. Therefore, you can generalize this by saying the solution is pi multiplied by an integer 'n' where 'n' can be from zero to infinity:
[tex]x=n\pi[/tex]
where n = 0, 1, 2, 3, 4, 5, etc..
(make sure you specify that 'n' can equal zero.)
For the second equation, add 1 to both sides to get:
[tex]2sin(x)=1[/tex]
Divide both sides by 2 to get:
[tex]sin(x)=\frac{1}{2}[/tex]
Sine of what gives 1/2? Sine of pi/6 gives 1/2, and so does 5pi/6. Therefore, the two solution here would be pi/6 plus a phase shift of 2pi, and 5pi/6 plus a phase shift of 2pi:
[tex]x=\frac{\pi }{6} +2n\pi[/tex]
[tex]x=\frac{5\pi }{6} +2n\pi[/tex]
The second problem states that:
[tex]cos(u)=\frac{4}{5}[/tex]
Cosine is defined as the adjacent side of a right triangle divided by the hypotenuse of the right triangle:
[tex]cos(u)=adjacent/hypotenuse[/tex]
After drawing a triangle, the adjacent side is 4, and the hypotenuse is 5. But first, lets rewrite sin(2u) using the double angle identity to get:
[tex]sin(2u)=2sin(u)cos(u)[/tex]
But we know the value of cosine of 'u', it is 4/5. Therefore:
[tex]sin(2u)=2sin(u)*\frac{4}{5}[/tex]
[tex]sin(2u)=\frac{8}{5} sin(u)[/tex]
To find the sine of 'u', use the triangle you should have constructed when I defined cosine as the adjacent over the hypoptenuse. Sine is defined as the opposite over the hypotenuse. We have:
[tex]sin(u)=opposite/hypotenuse[/tex]
We have the adjacent, we have the hyppotenuse, and we want the opposite. If we find the opposite side, we can find the sin(2u). Use pythagogrean's theorem to find the opposite:
[tex]adjacent^2+opposite^2=hypotenuse^2[/tex]
[tex]4^2+opposite^2=5^2[/tex]
[tex]opposite^2=25-16[/tex]
[tex]opposite=3[/tex]
Finally, we have that:
[tex]sin(u)=\frac{3}{5}[/tex]
Or:
[tex]sin(2u)=\frac{8}{5}*\frac{3}{5} =24/25[/tex]
Hopefully you could follow along. There is a lot going on here, but since youre in pre-calc, you should be able to follow along as long as you follow my steps.

Answer:
1. B = 61.5 ft²2. h = 12 ft3. V = 738 ft³Step-by-step explanation:
Firsly ,we notice that the base of the prism is a regular pentagon
regular means the five sides of the pentagon are equal in measure .
_______
Formula :
Area of a regular pentagon B = 1/2 × p × a;
where p is the perimeter of the pentagon
a is the apothem of the pentagon
_______________________________
then p = 5×6 = 30 ft
a = 4.1 ft. (Given)
therefore ,
B = 1/2 × p × a
= (1÷2) × 30 × 4.1 = 61.5 ft²
height of the prism h = 12 ft (given)
Volume V = B × h = 61.5 × 12 = 738.ft³

Answer:
You can divided 74 by 5. 5 fits into 7 once so you subtract 5 and you are left with 2. Then bring down the 4 and you have 24. 5 fits into 24 only 4 times so you would subtract 20 from 24 and be left with 4. Then add a decimal point and a 0. Bring down the 0 and you'll have 40. 5 fits into 40 exactly 8 times so 40 - 40 = 0. The answer is 14.8
