Height = 10cm
Diameter = 20.3cm

r= d/2 r = 20.3 / 2
r = 10.5cm

v = π x r x r x h
v = 3.14 x 10.15 x 10.15
v = 323.49cm2
v = 323.49 x 10
v = 3234.9cm3

Height = 10m
Diameter = 0.8 (inside) and 1 (outside)

Inside -
R = d/2
R = 0.8/2
R = 0.4

V = π x r x r x h
V = 3.14 x 0.4 x 0.4 x h
V = 0.5 x 10
V = 5m

Outside -
R = d/2
R = 1/2
R = 0.5

V = π x r x r x h
V = 3.14 x 0.5 x 0.5 x h
V = 0.78 x 10
V = 7.8m
