How to Make a Sphere in GeoGebra
GeoGebra
has two tools that can be used to draw spheres in the 3D-space:
If you want to draw an arbitrary sphere, choose Item 4.
If you know the radius and center, choose Item 4.
GeoGebra
Instruction 1
Sphere: Center & Point
Algebra View
and 3D Graphics
under View
in Menu
. Sphere: Center & Point
3D Graphics
. This point will be the center of the sphere. GeoGebra
Instruction 2
Sphere: Center & Radius
Algebra View
and 3D Graphics
under View
in Menu
. Sphere: Center & Radius
3D Graphics
. This point will be the center of the sphere. GeoGebra
will now ask you to type in the radius of the sphere. Type in the desired radius. The sphere will now appear in 3D Graphics
. Alternatively, you can type
Sphere(Point, Radius)
in Algebra View
where you type in the center of the sphere in the Point
field and the radius in the Radius
field.
Example 1
Draw a sphere with center at (1, 3, 2) and a radius of 2
Follow Item 4 for this exercise. Type in
Sphere(Point, Radius)
in Algebra View
. Then type in the values in the fields where they belong. The sphere will now appear in 3D Graphics
.
