A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is 30 feet, the height of the roof is 12 feet, and the height of the entire silo is 60 feet?
147,026.5 ft
135,716.8 ft
180,955.7 ft
169,646.0 ft
Answers
Answer:
The volume of the silo is approximately 147,026.6 ft.³.
The most correct option is 147,026.5 ft.³
Step-by-step explanation:
The given dimensions of the silo are;
The shape of the silo = Composite figure of tower and roof
The shape of the tower = Cylindrical
The shape of the roof = Cone
The radius of the base of the silo, 'r' = 30 feet
The height of the cone roof of the silo, h₁ = 12 feet
The height of the entire silo = 60 feet
For the cone roof, we have;
The volume of a cone, V = 1/3 × Base area × Height
The volume of the cone roof, V₁ = 1/3×π·r² × h₁
∴ V₁ = 1/3 × π × (30 ft.)² × 12 ft. ≈ 11,309.7336 ft.³
For the cylindrical tower, we have;
The height of the entire silo = The height of the tower + The height of the roof
∴ The height of the tower = The height of the entire silo - The height of the roof
The height of the tower, h₂ = 60 ft. - 12 ft. = 48 ft.
The volume of a cylinder = Area of base × Height
The volume of the cylindrical tower, V₂ = π·r² × h₂
∴ V₂ = π × (30 ft.)² × 48 ft. ≈ 135,716.803 ft.³
The volume of the cylindrical tower, V₂ ≈ 135,716.803 ft.³
The volume of the (entire) silo, Vₙ = V₁ + V₂
∴ Vₙ = 11,309.7336 ft.³ + 135,716.803 ft.³ = 147,026.573 ft.³
The volume of the (entire) silo, Vₙ ≈ 147,026.6 ft.³.
Answer:
147,026.5 ft.³

The diameter of a circle is 5 centimeters.
What is the circle's circumference? Use a = 3.14
Answer:
centimeters.
Answers
Answer:
half of 5 is 2.5
2.5 x 3.14 x 2 = 15.7 cm
Formula of circumference:
2(you just always need this number when finding circumference) x pi(3.14 or 22/7 depending on what they tell you to use) x r(radius, half of your diameter or given radius).
Answer:
15.7
Step-by-step explanation:
circumference = 2 x 3.14 x r ---? 2 x 3.14 x 2.5 = 15.7

Answers
Answer:
sin(A) = opp / hyp
=a/hyp. =9/15
cos(A) = adj/hyp
=b/hyp. =12/15
Tan(A) = sin(A) / cos(A)
= 9/15 / 12/15
=9/12. (you can further simplify it)
same for the B angle,
sin(B) = b/15
=12/15
cos(B) = a/15
=9/15
tan(B) = sin(B) / cos(B)
= 12/15 / 9/15
=12/9

Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the line
m = [tex]\frac{0-3}{6-0}[/tex] = [tex]\frac{-3}{6}[/tex] = - [tex]\frac{1}{2}[/tex] = - 0.5
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 0.5x + 3 ← equation of line

Figuras de ação = 15
Número total de brinquedos = (21 + 18 + 15) = 54 brinquedos
Número de brinquedos por prateleira = 18
Número de prateleiras:
Número total de brinquedos / número de brinquedos por prateleira
Número de prateleiras = 54/18

Sammy's mother asked him to buy some aspirin at the supermarket. There were two different
sizes of aspirin bottles, and Sammy was not sure which one to buy. The bottle with 150 tablets
cost $7.50. The bottle with 50 tablets cost $3.00. Sammy used proportions to make his decision.
1. The bottle with 150 tablets
2. The bottle with 50 tablets
3. Both bottles work out the same
Answers
so I divided 150 by 7.50 and it’s 20 tablets for 1.00 then I divided 50 by 3.00 and it’s 16 tablets for 1.00 so the bottle for 7.50 is a better deal

Complete question is;
A researcher wants to see if a kelp extract helps prevent frost damage on tomato plants. One hundred tomato plants in individual containers are randomly assigned to two different groups. Plants in both groups are treated identically, except that the plants in group 1 are sprayed weekly with a kelp extract, while the plants in group 2 are not. After the first frost, 12 of the 50 plants in group 1 exhibited damage and 18 of the 50 plants in group 2 showed damage. Let p1 be the actual proportion of all tomato plants of this variety that would experience damage under the kelp treatment, and let p2 be the actual proportion of all tomato plants of this variety that would experience damage under the no-kelp treatment. Is there evidence of a decrease in the proportion of
tomatoes suffering frost damage for tomatoes sprayed with kelp extract? To determine
this, yo u test the hypotheses H0: p1 = p2, Ha: p1 < p2. The p - value of your test is
A) greater than 0.10.
B) between 0.05 and 0.10.
C) between 0.01 and 0.05.
D)between 0.001 and 0.01.
E) below 0.001.
Answer:
B) between 0.05 and 0.10.
Step-by-step explanation:
We are given;
Number of plants in group that exhibited damage = 12
Number of group 1 plants; n₁ = 50
Number of plants in group 2 that exhibited damage = 18
Number of group 2 plants; n₂ = 50
Proportion of plants in group 1 that exhibited damage; p₁^ = 12/50 = 0.24
Proportion of plants in group 2 that exhibited damage; p₂^ = 18/50 = 0.36
Pooled proportion; p¯ = (12 + 18)/(50 + 50) = 0.3
q¯ = 1 - p¯
q¯ = 1 - 0.3 = 0.7
Z-score will be;
z = ((p₁^ - p₂^) - 0)/√((p¯•q¯)×((1/n₁) + (1/n₂))
Plugging in the relevant values;
z = (0.24 - 0.36)/√((0.3 × 0.7) × ((1/50) + (1/50))
z = -0.12/0.092
z = -1.3
From z-distribution table attached, we have;
p-value = 0.0968

As we all know, Pinocchio’s nose grows when he tells a lie.
So if he said “my nose will grow now” – if his nose does grow that would mean he wasn’t lying, but if he wasn’t lying, his nose wouldn’t grow.
But then his statement would be a lie… so his nose would grow.. but then the statement wouldn’t be a lie… so his nose wouldn’t grow… but yeah, you get the idea..
Basically, his nose would have to grow to make Pinocchio’s statement not a lie, but then it can’t grow otherwise the statement would not be a lie.
