jawab ya pake caranya juga thanks

Maaf kalo jawabannya ada yg salah :)

V=phi X r^(2) X t
= 3,14 X 10,5^(2) X 18
= 6231,33 cm3

V=phi X r^(2) X t
= 3,14 X 20^(2) X 27
=33.912 dm3
V= phi X r^(2) X t
9240 = 22/7 X 14^(2) X
t
9240 = 616t
t= 9240/616
t=15 dm

V= phi X r^(2) X t
2826 = 3.14 X r^(2) X 9
t= 2826/28,26
r^(2)= 100
r= 10
