Tlong jwb semua ya…

1. V = πr² x ( tt + tk/3)

V = 22/7 x (28/2)² x ( 24 + 20/3)

V = 22/7 x 14² x ( 72+20)/3

V = 616 x 92/3

V = 18.890,67 liter

2. V = 11³ + 11×10/2 x 11

V = 1.331 + 1.210/2

V = 1.331 + 605

V = 1.936 cm³

3. V = 14³ + 14² x (26-14)/2

V = 2.744 + 196 x 6

V = 2.744 + 1.176

V = 3.920 cm³

4. V = 11 x (10-5) x 4 + 18 x 5 x 4

V = (55 + 90) x 4

V = 145 x 4

V = 580 liter

5. V = 15 x 12 x 24/3

V = 180 x 8

V = 1.440 cm³
