w załączniku, raczej proste : >
1) V=1/2(a+b)*h*H V=1/2(3m+1m)*25m*12m V=2m*25m*12m=600m3 1m3=1000l 600m3=600000l
2) a = 14cm V1 = a³ = 14cm × 14cm × 14cm = 2744cm³ d = 14cm r = 7cm H = 14cm π≈3,14 V2 = πr²H = 3,14 × 7² × 14 = 2154,04cm³ 2744cm³ - 100% 2154,04cm³ - x x = 2154,04cm³ × 100% ÷ 2744cm³ = 78,5%
liczę na najj! :D
Zad:1
wzór V=1/2(a+b)*h*H
podstawiamy do wzoru
V=1/2(3m+1m)*25m*12m V=2m*25m*12m=600m3 1m3=1000l 600m3=600000l
Odp.Balen pomieści 600000l wody.
Zad:2
niewiem jak zrobić

2) a = 14cm
V1 = a³ = 14cm × 14cm × 14cm = 2744cm³
d = 14cm r = 7cm H = 14cm π≈3,14
V2 = πr²H = 3,14 × 7² × 14 = 2154,04cm³
2744cm³ - 100%
2154,04cm³ - x
x = 2154,04cm³ × 100% ÷ 2744cm³ = 78,5%
