# What shape is a sphere?

### What shape is a sphere?

A sphere is a **round, ball-shaped solid**.

### What is sphere example?

A sphere is a three-dimensional object with no vertices and edges. All the points on the surface of the sphere are equidistant from its center. Some real-world examples of a sphere include **a football, a basketball, the model of a globe**. Since a sphere is a three-dimensional object it has a surface area and volume.

### Where is a sphere?

A sphere (from Greek σφαῖρα—sphaira, « globe, ball ») is a geometrical object **in three-dimensional space that is the surface of a ball**. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.

### Is a sphere a circle?

In simple terms – a circle is a round object in a plane, while **a sphere is a round object in a space**. Circle, as a two-dimensional figure has only an area – πr2. Sphere, on the other hand, as a three-dimensional figure (object) has an area – 4πr2 and a volume – 4/3πr3.

### How do you identify a sphere?

**Sphere Facts**

- It is perfectly symmetrical.
- All points on the surface are the. same distance « r » from the center.
- It has no edges or. vertices (corners)
- It has one surface. (not a « face » as it isn’t flat)
- It is not a polyhedron.

### What is a sphere for kindergarten?

### Is an apple a sphere shape?

**Apples are relatively spherical except for that** characteristic dimple at the top where the stem grows. How do apples grow that distinctive shape? … A ubiquitous example is seen in the cusp of an apple, the inward dimple where the stalk meets the fruit.”

### How do you sphere?

### How many circles are in a sphere?

one circle

As a corollary, on a sphere there is exactly **one circle** that can be drawn through three given points. The proof can be extended to show that the points on a circle are all a common angular distance from one of its poles.

### How many sides has a sphere?

An edge is where two faces meet. For example a cube has 12 edges, a cylinder has two and a **sphere has none**.

### What is a real life example of a sphere?

- Some examples of
**a sphere**are: Earth the Moon basketballs soccer ball world globe

### How do you calculate a sphere?

- The formula for volume is 4/3 times pi times the radius cubed, or 4/3πr^3. The formula for surface is 4 times pi times the radius squared, or 4πr^2.
**Calculate**the radius of the**sphere**from the information given about the**sphere**.

### What are the attributes of a sphere?

- A sphere is a
**solid geometric figure**defined as the set of all points equidistant from a common center point. It is perfectly**symmetrical**, and its surface is**uniformly curved, without any edges, vertices or faces**. It is the shape made when a semi-circle is rotated around its diameter.

### Is a sphere and a circle the same shape?

- Circle and sphere are both
**round**in shape but whereas a circle is a figure, a sphere is an object. You can compare the two as a drawing of a tennis ball on a piece of paper and the ball itself in real life. A circle is a 2D figure whereas a sphere is a 3D object having volume.
