A sphere is a three-dimensional geometric shape that is formed by joining an infinite number of points located at a fixed distance from a central point. The distance between a point located on the surface of the sphere and the centre is known as the radius. A sphere does not have edges or vertices. In simpler terms, a sphere geometric shape can be formed by spinning a circle along its diameter. The surface area of a sphere can be evaluated with the help of the formula 4π r², while its volume is given as (4/3)π r³, where r is the radius of the sphere.

**Properties of a Sphere**

1. A sphere is symmetrical from every direction.

2. A sphere only has a curved surface area and does not contain any edges.

3. The points located on the curved surface of the sphere are equidistant from the centre.

4. Among all the three-dimensional shapes with the same surface area, the sphere tends to have the maximum capacity or volume.

**Examples of Sphere**

### 1. Balls

Balls used in a number of bowling games are a prominent example of a sphere geometric shape. For instance, bowling balls, cricket balls, volleyball, basketball, tennis ball, etc., are all constructed in the shape of a perfect sphere.

### 2. Globe

Our planet earth is shaped like a spheroid, which closely resembles a spherical three-dimensional geometric shape. For simplicity, the shape of our planet is assumed to be a sphere, which is why the globes are constructed like a sphere.

### 3. Balloon

Some of the balloons used for decoration purposes are spherical in shape.

### 4. Yarn

A yarn ball is round in shape and forms a prominent example of a sphere.

### 5. Bulb

Bulbs are usually constructed in oval, cylindrical, or spherical shapes.

### 6. Lollipop

The candy portion of a lollipop is generally shaped like a sphere and is attached to a cylindrical pipe.

### 7. Marbles

Marbles are yet another example of spherical objects used in daily life.

### 8. Fruits and Vegetables

A number of fruits and vegetables such as tomato, cherry, musk melon, watermelon, orange, etc., are shaped like a sphere. Although some of them are not perfect spheres and closely resemble the spheroid geometric shape.

### 9. Water Droplets

Water droplets are naturally spherical in shape.

### 10. Stones

Stones are available in nature in a variety of shapes and sizes out of which one of the most common and rare shapes is a sphere.

### 11. Chocolate

Chocolate manufacturing companies generally make use of the sphere geometric shape to produce chocolates and other edible food items.

### 12. Soap Bubbles

Soap bubbles are a perfect example of spherical objects present around us. Interestingly, no matter whether a soap bubble is blown out of a square loop, a cubical loop, or any haphazard shaped loop, it tends to maintain its spherical shape. This means that the natural tendency of a soap bubble is to exist in the shape of a sphere.

### 13. Pendulum Bob

A pendulum bob is yet another example of spherical objects present around us.

### 14. Eyeball

Our eyeballs are a perfect example of a sphere.

### 15. Christmas Decoration

A number of Christmas decoration items are spherical in shape.

### 16. Pom Poms

Pom poms, used by the cheer squad, are a classic example of spherical objects present around us.

### 17. Cotton Balls

Cotton balls used in daily life are usually spherical in shape.
