Question

Dau coroana si tot ce trebuie!! E urgent va rog!20 de puncte dau

Answer 1

a) A(ABCD)=50×30=1500 cm²
b)
V(BCDEFGH)=50×30×20=30000 cm³
Vcapac=jumatatea unui cilindru cu inaltime de 50 si raza =FG/2=30/2=15 cm
(15²×π×50)/2=5625π≈17662,5
Vtotal=30000+17662,5=47662,5 cm³
cea mai mare distanta este AJ
ducem JM_I_BC
JM=15+20=35 cm
BM=30/2=15
AM²=50²+15²=2725
AJ²=AM²+JM²=2725+35²=2725+1225=3950
AJ=√3950=62,849 cm  >62
deci un bat de  62 cm incape in cufar
