Does a sphere have a lateral face?
No, a sphere has no face. A face is a flat surface and a sphere has no flat surface. This makes the sphere a faceless three-dimensional shape.
What is the formula of lateral surface area of sphere?
The lateral surface area of sphere is expressed as LSA = 2πrh or 4πr2 (If a diameter of sphere = 2r).
Does a cylinder have a lateral area?
The lateral surface of an object is all of the sides of the object, excluding its base and top (when they exist). For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder: A = 2πrh.
Where is the lateral area?
Lateral indicates the side of something. Therefore, lateral surface area is found by finding the surface area of the sides of the object. This is done by finding the perimeter of the base and multiplying it by the height of any three-dimensional figure.
How many sides does a sphere have?
A sphere has no sides at all. It has an infinite number of infinitesimally small surface areas, if you will. A sphere has an inner and an outer surface.
Why is surface area of sphere?
The Greek mathematician Archimedes discovered that the surface area of a sphere is the same as the lateral surface area of a cylinder having the same radius as the sphere and a height the length of the diameter of the sphere. The lateral surface area of the cylinder is 2πrh where h=2r .
Does a sphere have a side?
A sphere has no sides at all. It has an infinite number of infinitesimally small surface areas, if you will.
How do you find lateral area?
You can find the lateral area of a solid with parallel bases by multiplying the perimeter of the base — the length around the edge of the base — by the solid’s height. The perimeter of a cube’s base is equal to four times the length of one of the cube’s edges, s.
How do you find the area of a sphere?
To find the surface area of a sphere you can use the following formula: Area = 4 π r². In an easier to read form: Area = 4 * Pi * r * r. Sometimes a sphere is given a north and south pole (found on opposite sides of the surface).
What is the definition of lateral area?
lateral area(Noun) The sum of the areas of the lateral (vertical) faces of a cylinder, cone, frustum or the like. lateral area(Noun) A particular part of the medulla oblongata.
What is the approximate surface area of the sphere?
The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15×15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards. 1.6. 16 votes.
