Dîtina qebareya tebeqeya gewr

In this publication, we will consider formulas that can be used to calculate the volume of a spherical layer (slice of a ball), as well as an example of solving a problem to demonstrate their practical application.

  • R radiusa topê ye;
  • r1 tîrêjê bingeha birrîna yekem e;
  • r2 tîrêjê bingeha birrîna duyemîn e;
  • h bilindahiya tebeqeya gewherî ye; perpendîkular ji navenda bingeha yekem heya navenda ya duyemîn.

Formula for finding the volume of a spherical layer

To find the volume of a spherical layer (slice of a ball), you need to know its height, as well as the radii of its two bases.

The same formula can be presented in a slightly different form:

Notes:

  • if instead of base radii (r1 и r2) their diameters are known (d1 и d2), the latter must be divided by 2 to obtain their corresponding radii.
  • jimare π bi gelemperî heya 3,14 têne dorpêç kirin.

Mînaka pirsgirêkê

Find the volume of a spherical layer if the radii of its bases are 3,4 cm and 5,2 cm, and the height is 2 binêre.

Çare

All we need to do in this case is to substitute the known values ​​into one of the formulas above (we will choose the second one as an example):
