Match the title to the correct description:

Groups:

(a) Spaceship Earth

,

(b) Sphere of the Plaza

,

(c) Soccer Ball

• 
• 
• 
• Consists of 11,324 flat triangular panels and located at Disney.

• Developed in the mid-19th century in England

Match the term with its definition:

Diameter - (a)  

Radius - (b)  

• Distance from the edge to the edge
• Distance from the center to the edge

To initiate the SPHERE command using the shortcut, type " (a)   " and press enter.

Place the following steps in the correct order to create a sphere:

• Set the center point

• Type "SPH" or select the "SPHERE" command

• Specify the radius

Match the modifier to its definition:

• TTR (Tangent, Tangent, Radius)

• Specifies the center point of the sphere

• 3P (Three Points)

• Defines the circumference of the sphere by specifying two points anywhere in 3D space.

• Center Point

• Defines the circumference of the sphere by specifying three points anywhere in 3D space. 

• 2P (Two Points)

• Defines the diameter of the sphere.

• D (Diameter)

• Defines the sphere with a specified radius tangent to two objects.

Match the question with the correct clarification:

• How do I create a half-sphere?

• Design your desired 2D shape and use the 'revolve' command to bring it to life.

• Can I make a sphere that's more oval?

• After creating your sphere, simply use the 'slice' command to achieve a half-sphere.

• Why can't I specify my sphere's height?

• Spheres naturally expand equally in all directions based on the radius, so there's no need for a separate height.

Draw a simple 2D sketch that represents a sphere.

Name three products that could be designed using the SPHERE command in AutoCAD.

What is a sphere?

• A sphere is a two-dimensional geometric shape.
• A sphere is a four-dimensional geometric shape.
• A sphere is a flat geometric shape.
• A sphere is a three-dimensional geometric shape that is perfectly round and symmetrical.
