Does a sphere have a curved surface
WebJan 5, 2011 · How many faces does a sphere have? For the classic geometric definition of a face (a flat planar surface), it has zero.But for the use of a face as a homogeneous curved surface, the sphere has one face. It does, however, have no edges or sides.Technically a sphere has no faces because a face is a flat surface. I hope this … Websurface area of the cube S 2 = 6 a 2 = 6 V 2 / 3. Comparing surface areas, S 1 < S 2 i.e. the surface area of a sphere is smaller than that of a cube for a given volume. Similarly, we can analytically compare surface area of a sphere with that of any other geometrical shape. The minimum surface area of the sphere results in the minimum surface ...

WebMay 5, 2010 · The curve on the surface of a spherical lens, if extrapolated in all directions, would form a ball or perfect sphere. The sphere would vary in size based on the steepness of the curve. A steeper, higher power curve would form a smaller sphere with a smaller radius, while a flatter, lower power curve would form a larger sphere with a larger radius. WebApr 12, 2024 · A cylinder is a 3D shape that has two circular faces, no vertices and two curved edges. A sphere is a 3D shape that has no faces, no vertices and no edges. A face is a flat surface on a 3D shape. A vertex is a point where two or more edges meet on a 3D shape. ... They can also sort them by whether they have curved or flat surfaces. Use …
WebA sphere is a solid figure bounded by a curved surface such that every point on the surface is the same distance from the centre. In other words, a sphere is a perfectly round geometrical object in three-dimensional … WebIn mathematics, curvature is any of several strongly related concepts in geometry.Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane.. For …
WebA sphere has 1 curved surface, 0 flat faces, 0 edges and 0 vertices. A sphere is a 3D circle. A sphere is ball-shaped and is perfectly round, which means that it is not longer in a particular direction than any other. A sphere contains no flat faces but it has one continuous curved surface. WebThe figure above shows a small sphere of mass m at a height H from the center of a uniform ring of radius R and mass M. The center of the ring is placed at the origin of a Cartesian coordinate system. The x and y directions line in the plane of the ring, while the z-direction is positive upwards. Part (a) Take the x-axis to be directed towards ...
WebDec 30, 2016 · The surface of the sphere is their whole world and existence. When these "sphere people" draw a circle, and then walk from the edge to the center of the circle, they don't travel in what we (the "3D" people) would observe to be a straight line. They travel along a curve (the surface of the sphere).

Further, the sphere has no "flat spots" or "angles" or "discontinuities" of any kind. It is a … flights from norfolk to ohioWebFind the volume of the sphere using the given radius. Solution: The radius of the sphere (r) = 10 inches. We know the formula for the volume of a sphere: v = 4/3 π r 3. Substituting the value of the radius in the above formula, we get: v= 4/3 π r 3 = 4/3 π (10) 3 = 4188.8 inches 3.
