r= 14cm
H= 40cm
π=3,14
V= πr² x H
V= 3,14 x (14cm)² x 40cm
V= 3,14 x 196cm² x 40cm
V= 3,14 x 7840cm³
V= 24617,6cm³
1l = 1000 cm³
24617,6cm³ = 24,6176l ≈ 25l
V=Pp*hh
V=πr²*h
V=3,14*14²*40
V=24617,6cm³
1l=1000cm^3
24617,6/1000=24,6176≈25l - odpowiedź w przybliżeniu
V= π * (14cm)² * 40
V= π * 196cm² * 40
V= 3,14 * 7840cm³
V= 24617,6cm³
24617,6cm³ ≈ 25l
