volume of cylinder : 756π

  • height : 21 cm
  • diameter : (4/7 * 21) = 12 cm
  • radius : d/2 = 12/2 = 6 cm

find volume:

[tex]\sf volume \ of \ cylinder : \pi r^2h[/tex]

[tex]\sf \hookrightarrow \pi (6)^2(21)[/tex]

[tex]\sf \hookrightarrow \pi (36)(21)[/tex]

[tex]\sf \hookrightarrow 756\pi[/tex]

Diameter:-

  • 4/7(21)=4(3)=12cm
  • Radius=r=6cm
  • Height=h=21cm

Now

Volume:-

  • πr²h
  • (3.14)(6)²(21)
  • 65.94(36)
  • 2373.84cm^3
