1 1/2 x a x h = 6 x 35 = 210dm
12 x 12 = 144dm
6 x 5 = 30dm
a)po dodaniu = 384dm kwadratowych
b) 38400 cm kwadratowych
c) 3,84 m kwadratowego
d) 0,0384 a kwadratowych
2 2 x 384dm ^2 + 50 (13 + 12 + 37 + 52) = 768 dm^2 + 6300dm^2 = 8068 dm ^2
3 0,8m x 2,5m = 2m^2
4 r= 0,4 m
p = pi x r^2
p =(22/7 x 0,16m^2) : 2
p = 0,25m^2
5 Sorry nie lape tego dokladnie ale powierzchnia tej sciany = 50(35 + 12 + 5) = 2600dm^2
6 P= Pi x r^2
Pd = 706,5 dm^2
Pm = 78,5 dm^2
706,5 = 3,14 x r^2
r^2 = 706,5 : 3,14
r^2 = 225
rduze = 15dm
78,5 = 3,14 x r^2
r^2 = 78,5 : 3,14
r^2 = 25
r = 5
7 dach = 384dm^2
sciany = 50(12+13+37)
sciany = 3100dm^2
3484 dm^2 = 34,84m^2
1m^2 = 0,2kg
x kg = 34,84 m^2 x 0,2 kg
xkg = w przyblizeniu 7kg farby
8 V = Pp x h
V = 384dm^2 x 50dm
V = 19200 dm^3
Mam nadzieje ze pomoglem :)
