Find the area of the end (area of a circle)
(pi)(r^2)
(pi)(1.5^2)
2.25(pi)
Multiply this by the height
(2)(2.25)(pi)
4.5(pi)
14.137166941154069573081895224758
14.137 <----
Converting to liters
(14.137 m^3)( 1000 L / 1 m^3) = 14137 L <----

The volume V = B*h , B = πr² , r=1.5 m, h=2 m
V = π*1.5²*2 = 14.1371 ≈ 14.137 m³
b) 14.137 m³ = 14137 dm³ = 14137 liters
V = π*1.5²*2 = 14.1371 ≈ 14.137 m³
b) 14.137 m³ = 14137 dm³ = 14137 liters
