A cylinder has two parallel circular bases connected by a curved surface, while a sphere is a perfectly round three-dimensional shape with all points on its surface equidistant from its center. In simple terms, a cylinder is like a can and a sphere is like a ball.

What is the difference between spherical and round?
"Spherical" refers to having the shape of a sphere, which is a three-dimensional shape with all points equidistant from its center. "Round" is a more general term that can be used to describe any shape with smooth, curved lines and no sharp edges. A sphere is always round, but not all round shapes are spherical.
Difference between thin and thick cylinder?
A thin cylinder has a wall thickness significantly smaller than its radius, while a thick cylinder has a wall thickness comparable to or larger than its radius. Thin cylinders typically use simpler stress analysis assumptions, whereas thick cylinders require more complex stress analysis methods to account for the effect of the thicker walls.
What is cylinder in eyeglasses?
The cylinder value in eyeglasses refers to the amount of astigmatism correction needed. It indicates the degree of astigmatism present in your eyes, which means there is an irregular curvature of the cornea or lens. The cylinder value works in combination with the axis value to ensure the correction is properly aligned for clear vision.
Explain how a Van de Graaff generator builds up a static charge.?
A Van de Graaff generator uses a motor to transfer positive charge from a grounded metal sphere to a rubber belt continuously. The charge builds up on the metal sphere as the belt moves, creating a high voltage difference between the sphere and the belt due to the continuous transfer of charge.
Why in coulomb's law for charges force is inversely proportional to square of distance between charges?
The inverse square law in Coulomb's law results from the spread of electrical field lines in three-dimensional space. As the distance between charges increases, the field lines originating from one charge become distributed over the surface area of an expanding sphere. This results in the density of field lines decreasing as the square of the distance, leading to the force between charges decreasing proportionally.
What is the difference between cylinder and a sphere?
A sphere has 0 vortex and a cylinder has 2 faces
What is the difference between a cone sphere and a cylinder?
sphere has 1 face and no vertex and it rolls but cone has 2 faces and it can roll and it has 1 vertex
What was Archimedes discovery about sphere and cylinder?
He discovered the relationship between a sphere and a circumscribed cylinder of the same height and diameter. The volume is 4⁄3πr3 for the sphere, and 2πr3 for the cylinder. The surface area is 4πr2 for the sphere, and 6πr2 for the cylinder (including its two bases), where r is the radius of the sphere and cylinder. The sphere has a volume and surface area two-thirds that of the cylinder. A sculpted sphere and cylinder were placed on the tomb of Archimedes at his request.
What is the difference between a sphere and in a hemisphere?
A hemisphere is half a sphere
What is the difference between a hemisphere and a sphere?
Sphere is whole a hemisphere is not
What is relationship between cone and sphere?
Actually seeing the relationship between the volumes of a cone (one-third of a cylinder) and a sphere (two-thirds of a cylinder) is hard to beat. The cylinder is 1/3 the volume of the cone
What is the similarities between a cone a cylinder and a sphere?
They are all 3D geometric shapes.
Is there a difference between a cylinder head a head cylinder?
No
similarities between a sphere and a cylinder?
. A cylinder is similar to a prism, but its two bases are circles, not polygons.While The sphere is a space figure having all its points an equal distance from the center point.
What is the difference between a square pyramid and a square sphere?
They are very different, as a square sphere is impossible. The difference is that a square pyramid exists, whereas there's no such thing as a square sphere.
Difference between cube and sphere?
A cube is a three dimensional square, and a sphere is a three dimensional circle.
Difference between a sphere and a cone?
A sphere to a cone is the same as a circle is to a triangle but they are both 3 dimensional.
