 # How To Make A Hoberman Sphere

A hoberman sphere is a simple toy made from metal wire and plastic sheets. It can be opened and closed to change its shape. The hoberman sphere is named after john hoberman, who designed it in the early 1980s.

## How To Make A Hoberman Sphere

A Hoberman sphere is a collapsible toy that can be made from a metal ring and several pieces of fabric. The ring is bent into a circular shape and the fabric is attached to create six panels. The panels are then folded inwards, creating a ball-like shape. The sphere can be opened and closed by rotating it so that the panels line up.

-A large piece of cardboard or poster board -X-acto knife -Ruler or tape measure -Scissors -Pens or pencils -Markers or crayons -Tape

• Cut out the circle
• Draw another circle that is 10 inches in diameter inside the first circle
• Cut out the smaller
• Take a piece of cardboard and draw a circle on it that is 18 inches in diameter

1. Select the size of your Hoberman sphere. The size you choose will determine the number of spokes needed for the construction. 2. Cut the spokes to the correct length. You will need one spoke for every inch of diameter of your sphere. If you are making a six-inch sphere, then you will need six spokes. 3. Connect the spokes at the ends to form a circle. 4. Use a hot glue gun to attach the ends

### How Do You Change Expanded Form To Standard Form Of A Circle?

To change the standard form of a circle from its expanded form, one simply needs to divide all the terms in the expanded form by the number that is found in the square root of the circle’s radius.

### How Do You Find The Expanded Form Of A Circle?

The expanded form of a circle is the area of the circle.

### How Do You Expand A Circle?

There are a few ways to do this. One way is to use the Pythagorean theorem to find the hypotenuse of a right triangle and then use that length to find the radius of the larger circle. Another approach is to draw two circles with the same center and then find the points where they intersect. Finally, you could use calculus to find the equation of a circle and then use that equation to find the radius of a larger circle.

### How Do You Write The Standard Form Of The Equation Of The Circle With The Given Center And Radius?

The equation of a circle is: (x-h)² + (y-k)² = r².

### How Do You Rewrite A Circle Equation In Standard Form?

The equation for a circle is x2 + y2 = r2, where r is the radius of the circle. To rewrite this equation in standard form, we need to remove the square brackets and square root symbols. This can be done by factoring out the x2 term: x2 + y2 = (x + y)2.

### How Does A Hoberman Sphere Work?

A Hoberman Sphere is a type of collapsible toy that consists of several metal plates connected by hinges. When the toy is collapsed, it can be transported in a small bag. When it is expanded, the metal plates form a sphere.

### How Do You Write The Standard Form Of The Equation Of A Circle With The Center And Radius?

The equation of a circle with the center (h, k) and radius r is given by: (x – h)^2 + (y – k)^2 = r^2

### Who Made The Hoberman Sphere?

Hoberman spheres are an invention by artist and inventor, Jim Hoberman.

### How Do You Write The Equation Of A Circle In Standard Form With Center And Radius?

The equation of a circle in standard form with center and radius is (x-h)² + (y-k)² = r².

## In Closing

A Hoberman sphere is a simple toy that can be made with a few basic supplies. It consists of a metal hoop, four wire rings, and a piece of string. The hoop is twisted into a small circle and the wire rings are attached to the outside. The string is then tied around the middle of the circles to hold them together. When the string is released, the circles will expand and form a sphere.
