# In the figure 7.12, a cylindrical wrapper of flat tablets is shown. The radius of a tablet is 7 mm and its thickness is 5 mm. How many such tablets are wrapped in the wrapper?

Answer :

Since there are only flat tablets which are stacked onto each other inside the cylindrical wrapper, so the radius of the wrapper does not matter.

Height of wrapper, H = 10cm = 100mm

Thickness of the tablet, h = 5mm

⇒ Number of the tablets = 20

∴ There are 20 tablets inside the cylindrical wrapper.
