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.

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 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.
