Question

Pliss ya ka jawab yg mana aja kalau boleh semua... soalnya aku ga ngerti

Answer 1

2.) V= L.alas x t
720= 30 x t
720=30t
t=720÷30
=24
3) V= L.alas x t
V=26 x 38
=988

maaf kalo salah

Answer 2

1. v= phi.r^2.t
v= 3,14 ×10×10×50
v= 15700 cm^3
2. v= La×t
720= 30×t
30×t= 720
t= 720:30
t= 24cm
3. v= La.t
v= 26×38
v= 988 cm^3
4.
v= 1/4.phi.d^2.t
6594= 1/4.3,14.d^2.21
6594= 65,94×d^2 :4
d^2= 6594×4: 65,94
d=√400 = 20

5.
v= La×t
4710=314×t
314×t= 4710
t= 4710:314
t= 15
