Answer: Volume = 97.6
Step-by-step explanation:
Volume of the cone first
V = 1/3 h π r²
h = 0.7
r = 2
V = 1/3 × 0.7 × 2² × 3.14
V = 1/3 × 0.7 × 4 × 3.14
V = 1/3 × 8.792
V = 2.93
Then find the volume of the cylinder if the cone was there.
V = π r² h
r = 2
h = 8
V = 3.14 × 2² × 8
V = 3.14 × 4 × 8
V = 3.14 × 32
V = 100.48
Now you subtract the volume of the cone from the cylinder.
100.48 - 2.93 = 97.55
Rounded to the nearest tenth is 97.6

Answers
Answer:
Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30

A party hat has a height of 7 inches and a diameter of 6 inches. What is the volume of the party hat in cubic inches? Use 3.14 for pie.
Answers
Answer:
65.94 in³
Step-by-step explanation:
First, we need to determine to the shape, a party hat is a cone.
The volume formula that use to calculate the cone is 1/3hπr².
Notice: h is for height and r is for radius
Using this formula, we can easily set up the equation below:
1/3 · 7 · 3.14 · (6/2)² = 65.94 (cubic inches)
You must halved the diameter first (in this case, 6) and then square it.
So: The answer of this question is 65.94 in³

-You cant really see what 1 says but it says (The net below can be folded to make the triangular prism? Label the dimensions of the prism.)
And 8 says (Calculate the total area of the net and the surface area of the triangular prism from Problem 7. area net= surface area= ___ cm^2)
Answers
Answer:
1. Left side = 3 inches, Bottom side = 4 inches, Right side = 2 inches, Top side = 5 inches
2. A = 6 inches²
3. A = 8 inches²
4. A = 10 inches²
5. A = 12 inches²
6. A = 36 inches²
7. Left side = 5 cm, Bottom side = 12 cm, Right side = 4 cm, Top side = 13 cm
8. A = 180 cm²
Step-by-step explanation:
1. Label the dimensions of the prism:
Left side = 3 inches
Bottom side = 4 inches
Right side = 2 inches
Top side = 5 inches
2. Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 3 x 2
A = 6 inches²
3. Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 4 x 2
A = 8 inches²
4. Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 2
A = 10 inches²
5. (They gave the formula of the two triangles, but the question said green rectangle? They must've meant yellow triangles)
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 3 x 4)
A = 2(1/2 12)
A = 2(6)
A = 12 inches²
6. Total surface area of the triangular prism:
Formula:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 6 inches² + 8 inches² + 10 inches² + 12 inches²
A = 36 inches²
7. Label the dimensions of the prism:
Left side = 5 cm
Bottom side = 12 cm
Right side = 4 cm
Top side = 13 cm
8. Total surface area of the triangular prism:
First, we can find the area of each shape, as we had previously to find the total area of the net and the surface area of the triangular prism.
Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 4
A = 20 cm²
Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 12 x 4
A = 48 cm²
Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 13 x 4
A = 52 cm²
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 5 x 12)
A = 2(1/2 60)
A = 2(30)
A = 60 cm²
Total surface area of the triangular prism:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 20 cm² + 48 cm² + 52 cm² + 60 cm²
A = 180 cm²

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-10y=-20
Answers
Slope-intercept form:
y = mx + b
First, you must get y alone by subtracting 2x on both sides of the equation and then dividing both sides by -10:
-10y = -2x - 20
y = -2/-10x - 20/-10
Simplify: y = 1/5x + 2
Answer: y = 1/5x + 2

Find the surface are of this figure
Answers
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
