答案：

计算圆柱的体积。
r = 1 m,h = 2 m
V = ( )m³
r = 2 dm,h = 10 dm
V = ( )dm³
r = 10 cm,h = 10 cm
V = ( )cm³
d = 0.2 cm,h = 10 cm
V = ( )cm³
d = 20 dm,h = 5 dm
V = ( )dm³
S底 = 8 cm²,h = 7 cm
V = ( )cm³
S底 = 3.14 m²,h = 20 m
V = ( )m³
S底 = 2.5 dm²,h = 4 dm
V = ( )dm³
S侧 = 18.84 cm²,h = 3 cm
S底 = ( )cm²
V = ( )cm³
S侧 = 31.4 cm²,h = 5 cm
S底 = ( )cm²
V = ( )cm³
