Diameter = 21 cm
Radius = 21/2 cm
Height = 8 cm
Volume = πr²h = 22/7 x 21/2 x 21/2 x 8 = 2772 cm³
Radius = 21/2 cm
Height = 8 cm
Volume = πr²h = 22/7 x 21/2 x 21/2 x 8 = 2772 cm³

V=πr²h
--------------------
r = 21/2 = 10.5 cm
h = 8 cm,
------------------------------------
applying it in formula we get
3.14 x (10.5 )² x 8
3.14 x 110.25 x 8
2778.3 cm³
------------------------------------
the volume of cylinder is 2778.3 cm³
