yang Pinter MTK bntu kak!

V1 = 24cm^3
1/3 . pi . r^2 . t = 24
1/3 . pi . (d/2)^2 . t = 24
1/3 . pi . d^2 /4 . t = 24
1/12 . pi . d^2 . t = 24

V2 --> d --> 3d
t --> 2t

1/12 . pi . (3d)^2 . 2t = ...
1/12 . pi . 9d^2 . 2t = ...
18 . (1/12 . pi . d^2 . t) = ...
18 x 24 = 432 cm^3 (c.)

Vkerucut 24cm
kerucut diperbesar r=3r , t=2t

Vbaru= 1/3 pr^t
= 1/3 p(3r)^(2t)
= 1/3 p(9r^) (2t)
= 18×1/3 pr^t

=18×24
= 432cm^3.
