Bułgaria kojarzy się głównie z plażami nad Morzem Czarnym. Wciąż jest to największa atrakcja kraju. Ale warto rownierz zwrocic uwage na bardziej tradycyjne oblicze bulagrii.można tam odnaleźć odosobnione miejscowości ze starą, oryginalną, nieco przykurzoną, ale za to bardzo nastrojową zabudową. Górskie monastyry zapewniają chwile zamyślenia i tak poszukiwanego spokoju. Sa tam rownierz bardzo rozlegle jaskinie ktorych zwiedzanie dostarcza naprawde wiele przyjemnosci. Wszytkie te natrualne piekna byly tym co w bulgarii podobalo mi sie najbardziej. Podczas pobytu w bulgarii szczegolnie podobaly mi sie wieczorne wyjscnia na gre w bilard, naprawde swietnie sie wtedy bawilismy. Jednak bywaly tez nudne momenty takie jak, spotkanie z burmistrzem. Dyskoteka byla rownie swietnym pomyslem co prawie wszystkie pozostale ale za wczesnie sie skonczyla. Podsumowujac to wszystko naprawde ciesze sie z poznania bulgarskich kolegow i kolezanek, i ciesze sie z tej wymiany bardzo chetnie bym ja powtorzyl.Bardzo prosze przetlumaczyc mi to na angielski nie przez translate czy cos tego typu ja najszybciej plis;)

Answer

asa3helpme R=a $\sqrt{3}$ /6

4=a(pier(3)/6 /*6
24=a(pierw)(3)
24/pierw(3)=a
a=24(pierw(3)/3
a=8pierw(3)

obw=3*a=24pierw(3)
P=48pierw(3)

hans R=4
OBL P i obw
Patrz zalacznik
r=1/3h h=a/2·√3⇒r=a/6·√3
wiec 4=a/6·√3⇒a=24/√3=8√3

P=a²/4·√3=64·3/4·√3=48√3
obw=3a=24√3
