Question

Высота цилиндра равна 4 м , расстояние между осью цилиндра и параллельной ей плоскостью сечения равно 3 м, а площадь сечения 32 м².Найдите площадь боковой поверхности цилиндра. решение и полное объяснение

Answer 1

AB=4
OK=3
S сеч=AB*AC
4*AC=32
AC=8
AOC- равнобедренный, так как AO=OB ( как радиусы)
OK - высота и медиана
по теореме Пифагора
AO= \sqrt{3^2+4^2} =5
R=5
V=πR²*H
V=π*25*4=100π

Answer 2

Calculation of the lateral surface area of a cylinder

To find the lateral surface area of a cylinder, we need to know the height of the cylinder, the distance between the axis of the cylinder and a parallel plane of the section, and the area of the section.

Given: - Height of the cylinder (h) = 4 m - Distance between the axis of the cylinder and the parallel plane of the section (d) = 3 m - Area of the section (A) = 32 m²

We can use the formula for the lateral surface area of a cylinder, which is given by:

Lateral Surface Area = Perimeter of the Section x Height of the Cylinder

To find the perimeter of the section, we need to know the radius of the section. However, the radius is not provided in the given information. Therefore, we cannot calculate the lateral surface area of the cylinder with the given information.
