## How many curved surface has a sphere?

A sphere has no edges and therefore no corners. It has one curved face that goes all the way around.

## Does a sphere have 1 curved face?

Spheres: • are perfectly round: • have no edges; • have no vertices; • have 1 curved surface.

Is a sphere flat or curved?

Thus, a sphere has a curved faces. A cylinder has three faces. If a cylinder stands erect, its bottom face and top face are like circles. The bottom and top faces of a cylinder are flat.

### What is a shape with 1 curved side?

This 2D shape is a circle. A circle is the name we give to a 2D shape with one curved side and no corners. For a shape to be a circle it must also look exactly the same when we rotate it around. A circle does not have any straight sides.

### What is a curved surface area?

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases.

Does a sphere have a surface?

The shape of a sphere is round and it does not have any faces. Sphere is a geometrical three dimensional solid having curved surface. Like other solids, such as cube, cuboid, cone and cylinder, a sphere does not have any flat surface or a vertex or an edge.

## Does a sphere has a face?

A face is referred to as a flat or curved surface on a three-dimensional object. For instance, a cube has 6 faces. Thereby, a sphere has only one face which is a curved surface. It does not have any flat faces.

## Can triangles have curved sides?

A triangle is a polygon with three edges and three vertices. A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain (or polygonal circuit). From those two definitions, it should be clear that no, a “curved triangle” is not a triangle.

What do you call a curved face?

• a cone has one curved surface, a flat face with a curved edge (usually, but not always, a circle) and. an apex. To make it clearer, the face can be called a base and the point is the apex, not a vertex. • a cylinder has one curved surface, two curved edges (always circles) and no vertices.

### Can a shape have a curved side?

Two-dimensional curved shapes include circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments. Three-dimensional curved shapes, including spheres, cylinders and cones, are covered on our page on Three-Dimensional Shapes.

### How do you find a curved surface area?

The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where ‘r’ is the radius of the base and ‘h’ is the height of the cylinder.

How many curved edges does a sphere have?

1 Answers. There is no specific “edge” on a sphere. Every single point is curved off, but there is no specific edge.

## How to calculate the size of a sphere?

It will also give the answers for volume, surface area and circumference in terms of PI π. A sphere is a set of points in three dimensional space that are located at an equal distance r (the radius) from a given point (the center point).

## Is the cube a flat or curved surface?

A face is referred to as a flat or curved surface on a three-dimensional object. For instance, a cube has 6 faces. Thereby, a sphere has only one face which is a curved surface. It does not have any flat faces.

What makes a sphere a three dimensional object?

A sphere is a three-dimensional round-shaped object. Unlike other three-dimensional shapes, a sphere does not have any vertices or edges. All the points on the surface of the sphere are equidistant from its center. In other words, the distance from the center of the sphere to any point on the surface of the sphere is equal.

How many curved surface has a sphere? A sphere has no edges and therefore no corners. It has one curved face that goes all the way around. Does a sphere have 1 curved face? Spheres: • are perfectly round: • have no edges; • have no vertices; • have 1 curved surface. Is a sphere…
