L.A.= 2*pi*radius*height
its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.
Cylinder
A cross section of a cylinder along its length is called a rectangle. When a cylinder is cut along its length, the resulting shape is a rectangle with a length equal to the circumference of the cylinder and a height equal to the height of the cylinder. The area of this rectangle represents the lateral surface area of the cylinder.
There cannot be such a shape. It is not a cylinder because a cylinder sdoes not have a rectangular face. A rectangle must be a flat face and the only flat faces in a cylinder are the circle faces. The curved face can be "opened out" into a rectangular shape but because the face is curved it cannot be rectangular.
The lateral area is the surface area of a 3D figure, excluding the area of any bases. For the lateral area of a cylinder, you would take the circumference of the base multiplied by the height of the cylinder to get the lateral area of the surface. It's basically splitting a can down one side, cutting the ends off completely, rolling it out flat, and figuring out the area of the resulting rectangle.
The length of a rectangle formed from the lateral surface of a cylinder is equal to the circumference of the cylinder's base. This circumference can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the cylinder. The height of the cylinder corresponds to the height of the rectangle. Thus, the rectangle's dimensions are the circumference of the base for its length and the height of the cylinder for its height.
False. The lateral face of a cylinder, when spread out, forms a rectangle, not a circle. The height of the cylinder becomes one dimension of the rectangle, while the circumference of the base of the cylinder becomes the other dimension.
Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.

Cylinder
Name of faces of a cylinder are: 1.rectangle(lateral face) 2.circle(at the base and on top)
the circumfrance of the base x the height of the cylinder
2 (pi) (radius) (height)
The lateral surface area of a cylinder is the area of a rectangle. In other words: when a cylinder is unravelled, you are left with a simple rectangle with width and length. Depending on what kind of cylinder you happen to have, the circumference of the cylinder could be the width or the length. Where you have a short cylinder with a wide mouth, the circumference would become the length and the h would become the w. So, think of a cylinder as a rectangle. Take a piece of paper (rectangular) and bring the ends together. What do you have?: a cylinder. Now - for the formula: Diameter= D, Circumference= C, pi= 3.14 These are the parameters of a circle. Now, in mathematics, the radius of the circle and 2 *Pi is used in order to find the circumference of the circle. So, (D * pi)= 2Pi *r = C Therefore, the circumference or perimeter equals the width and the height or h = length of a rectangle. Now, then: The Formula for the Lateral surface of a cylinder Is: (2*Pi*r)*h= A Remember that the radius is half the Diameter of a circle and must be multiplied by two in order to convert back to D or Diameter. Please, note that ( 2*pi )= 360 degrees, and that it (2*Pi) also represents one whole revolution around the perimeter of a circle. To simplify: Diameter X (3.14) X height = Lateral Area of a cylinder. I hope this is of some help!
A cross section of a cylinder along its length is called a rectangle. When a cylinder is cut along its length, the resulting shape is a rectangle with a length equal to the circumference of the cylinder and a height equal to the height of the cylinder. The area of this rectangle represents the lateral surface area of the cylinder.
2 cirles and for the part in the middle if you look at it as a net it will be a rectangle just rolled up. That is called a lateral surface or a lateral face
The formula is AL = 2*Pi*radius*height
