Pls help?? A 3D shape has the net shown below.

tia_tia [17]

This question is incomplete because it lacks the picture of the appropriate diagram.

Find attached the diagram of the 3D shape.

Answer:

Edges: 6

Faces: 7

Vertices : 6

Step-by-step explanation:

3 Dimensonal (3D) shapes are shaped such that have faces, edges and vertices. From the numbers of faces, edges and vertices a 3D image has, you can tell or determine the type of solid shape it is.

Face: A face is the flat surface of a solid figure. Faces of 3D shapes comes in various forms such as triangles, rectangles, and pentagons.

Edge: An edge is defined as the straight line where two faces are connected to each other.

Vertices or a vertex: This can be defined as the point where edges connect or meet.

The 3D image in the question has :

6 Edges, 7 faces and 6 Vertices

A cylinder has diameter of 4ft and a height of 9ft. Explain whether halving the diameter has the same effect on the surface area

elena55 [62]

Answer:

See Below

Step-by-step explanation:

The surface area of cylinder is given by the formula:

$SA=2\pi r^2 + 2\pi r h$

Where

r is radius ( diameter is 4, so radius is 4/2 = 2)

h is height ( h = 9)

Lets find original surface are:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (2)^2 + 2\pi (2) (9)\\SA=8\pi +36\pi\\SA=44\pi$

<u>Halving diameter:</u>

diameter would be 4/2 = 2, so radius would be 2/2 = 1

So, SA would be:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (1)^2 + 2\pi (1) (9)\\SA=2\pi +18\pi\\SA=20\pi$

<u>Halving height:</u>

Height is 9, halving would make it 9/2 = 4.5

Now, calculating new SA:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (2)^2 + 2\pi (2) (4.5)\\SA=8\pi + 18\pi\\SA= 26\pi$

Original SA is $44\pi$ ,

Halving diameter makes it $20\pi$

Halving height makes it $26\pi$

So, halving diameter does not have same effect as halving height.
