According to the given statement the area of the cross section of the cone is 72 square units.
What does the word cone actually mean?a solid produced by rotating one of the legs of a right triangle. A solid that is surrounded by a circle and other closed planar base and indeed the surface created by line segments connecting each point here on base's perimeter to a single vertex is known as a right circle cone; for more information, see the Density Formulas Table.
Briefing:From the given information the height is 16 inches and the radius is 4.5 inches becuase the cone is sliced by a plane that passes through the center of the base, and also passes through the top vertex
So, The radius would be half the base, so the base would be 4.5 * 2 = 9 inches.
The area of the cross section of the cone is found by multiplying the base by the height, then dividing by two.
Area of the cross section of the cone = (9 x 16)/2 = 144
144 / 2 = 72 square inches.

A.
relation between hypotenuse and base is given by cos angle
so
[tex] \cos(ø) [/tex]=base/hypotenuse=11/x
cos37°=11/x
x=11/(cos37°)=13.77units
side indicated =x=13.77units

Answer:
[tex] m\angle EFG = 52\degree[/tex]
Step-by-step explanation:
By inscribed angle theorem:
[tex] m\angle EFG =\frac{1}{2} m\angle EDG[/tex]
[tex] (x+51)\degree =\frac{1}{2}(10x +94)\degree [/tex]
[tex] (x+51)\degree =\frac{1}{2}\times 2(5x +47)\degree [/tex]
[tex] (x+51)\degree =(5x +47)\degree [/tex]

Roscoe is locked outside his house.The only unlocked window is on the 2nd floor which is 24 feet from the ground. He will have to borrow a ladder from the neighbors house and place it 7 feet from the house. What length of ladder does he need to reach the 2nd floor safely
Answer:
25 feets
Step-by-step explanation:
The scenario above can be modeled and solved Using Pythagoras :
Height to second floor = 24 feets
Horizontal Distance between foot of ladder and wall = 7 feets
Let length of ladder = x
The lengtb of ladder here is the hypotenus
Recall:
Hypotenus = sqrt(opposite² + adjacent²)
Hence,
x = sqrt(24² + 7²)
x = sqrt(576 + 49)
x = sqrt(625)
x = 25
Hence, length of ladder = 25 feets

Step-by-step explanation:
All 3 angles add up to be 180 due to sum of angles in a triangle.
Given this fact,
[tex]38 - 5x + 83 + 24 = 180 \\ 145 - 5x = 180 \\ - 5x = 180 - 145 \\ - 5x = 35 \\ x = 35 \div - 5 \\ = - 7[/tex]
Answer:
(38 - 5x)⁰ + 83⁰ + 24⁰ = 180⁰
<=> (38 + 83 + 24) - 5x = 180
<=> 145 - 5x = 180
<=> 5x = 145 - 180
<=> 5x = - 35
<=> x = - 7

The volumes of two similar solids are 512cm^3 and 2,197cm^3. If the smaller solid has a surface area is 960cm^2, find the surface area of the larger solid.
PART I: find the similarity ratio by taking the cube root of each volume. Show your work.
PART II: Use your answer from Part I to find the ratio of the surface areas. Show your work.
PART III: Set up a proportion and solve to find the surface area of a larger solid.
Answer:
2535 cm²
Step-by-step explanation:
Part 1
Cube root the ratio to find the length factor as volume factor = length factor³
∛512 : ∛2197 = 8 : 13
Part 2
Square the ration as area factor = length factor²
8² : 13² = 64 : 169
Part 3
Apply the ratio
64 : 169
960 / 64 = 15
15 x 169 = 2535
A candy company can sell fruit gums in rectangular boxes or in cylindrical tubes. Each box is 8 cm by 3 cm by 7 cm. Each cylinder has radius 3 cm and height 6 cm. The company wants the packaging that uses less material. Which packaging should the company choose? Justify your choice.
Answer:
i. The company should use the cylindrical tubes.
ii. This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
Step-by-step explanation:
i, Which packaging should the company choose?
The packaging that uses less material is the one with the least surface area. So, we find the surface area of each material.
For the rectangular box, the surface area, A = 2(lb + lh + bh) where l = length, b = breadth and h = height. Since each box is 8 cm by 3 cm by 7 cm,l = 8 cm, b = 3cm and h = 7cm.
So, ,A = 2(lb + lh + bh)
,A = 2( 8 cm × 3 cm + 8 cm × 7 cm + 3 cm × 7cm)
A = 2(24cm + 56 cm + 21cm)
A = 2(101 cm²)
A = 202 cm²
For the cylindrical tube, the surface area, A' = 2πr(r + h) where r = radius of cylinder and h = height of cylinder.
Since each cylinder has radius 3 cm and height 6 cm, r = 3cm and h = 6 cm.
So, A' = 2πr(r + h)
A' = 2π(3 cm)(3 cm + 6cm)
A' = (6π cm)(9 cm)
A' = 54π cm²
A' = 169.65 cm²
Since the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
The company should use the cylindrical tubes.
ii. Justify your choice.
This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
What is FG?
NEED HELP QUICK!!
Answer:
FG = 18
Step-by-step explanation:
FD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{24}{54}[/tex] = [tex]\frac{x}{x+10}[/tex] ( cross- multiply )
54x = 24(x + 10)
54x = 24x + 240 ( subtract 24x from both sides )
30x = 240 ( divide both sides by 30 )
x = 8
Then
FG = x + 10 = 8 + 10 = 18
