z tego wzoru obliczam:
a) r=1, H=5
V=π*1²*5
V=5π
V≈15,71
B) r=5 , H=1
V=π*5²*1
V=25π
V≈78,54
c) d=4 , H=2
r=d/2=2
V=π*2²*2
V=8π
V≈25,13
D) d=2 H=4
r=d/2=1
V=π*1²*4
V=4π
V≈12,57
V = π*r²*H
a) r=1, H=5
V= π*1²*5 = 5π
B) r=5 , H=1
V = π*5²*1 = 25π
c) d=4 , H=2, r = 0,5*d = 2
V = π*2²*2 = 8π
d) d=2 , H=4, r = 1
V = π*1²*4 = 4π
