Question

Формула площі повної поверхні циліндра

Answer 1

Ответ:

Sпов. = 2πR(Н + R)

Объяснение:

S полн. = S бок. + 2•S осн.

S бок. = 2πRH, где R - радиус основания цилиндра, Н - его высота.

S осн. = πR², тогда

S полн. = 2πRH + 2πR²

Иногда пишут так:

S пов. = 2πR(Н + R).

Answer 2

Formula for the Surface Area of a Cylinder

The formula for the surface area of a cylinder is given by:

Surface Area = 2πr(r + h)

Where: - π represents the mathematical constant pi, approximately equal to 3.14159. - r is the radius of the base of the cylinder. - h is the height of the cylinder.

This formula calculates the total surface area of the cylinder, which includes the areas of both the curved surface (lateral surface) and the two circular bases.

Please note that the formula assumes a right circular cylinder, where the base is a perfect circle and the height is perpendicular to the base.
