Question

Tolong bantuan nya ya...

Answer 1

Volum terisi air
r = 35 cm = 3,5dm
t = 1,2 m = 12dm
volum = 2/3 x phi x r x r x t
         = 2/3 x 22/7 x 3,5 x 3,5 x 12
         = 2 x 11 x 3,5 x 4
         = 88 x 3,5
         = 308
air habis = 308/30
             = 10,266
             = 10menit 16 detik

Answer 2

Volume =
= 3,14 x 35 x 35 x 120
= 461814,1201 cm kubik
= 461,8141201 liter
terisi 2/3 bagian = 307.876 liter = 308 liter
308/30 = 10.26 menit = 10 menit 16 detik
