Question

find the volume of the right circular cylinder has the base radius of 21m and height 14m.​

Answer 1

Given,

Base radius r= 21m

Height h =14m

To Find,

The volume of the right circular cylinder

Solution,

The base radius of the  cylinder

r = 21m

Height of the cylinder h= 14m

The volume of the cylinder = $\pi$r²h

$\pi$r²h = 3.14×21²×14

  =3.14×21×21×14

  = 19386.36m³

The volume of the right circular cylinder has a base radius of 21m and a height of 14m is 19386.36m³
