9. 3,14 x 10,5 x 10,5 x 1/2 x 2 = 138,474 cm 10. (3,14 x 4,5 x 4,5 x 1/2 x 2) + ((9+9) x 6) = 63,585 + 108 = 171,585 cm 11. (22/7 x 7 x 7 x 1/2) + (14 x 9 : 2) = 77 + 63 = 140 cm 12. (6 x 12 : 2) + (12 x 21) + (3,14 x 6 x 6 :2) = 36 + 252 + 56,52 = 344,52 cm
10. (3,14 x 4,5 x 4,5 x 1/2 x 2) + ((9+9) x 6) = 63,585 + 108 = 171,585 cm
11. (22/7 x 7 x 7 x 1/2) + (14 x 9 : 2) = 77 + 63 = 140 cm
12. (6 x 12 : 2) + (12 x 21) + (3,14 x 6 x 6 :2) = 36 + 252 + 56,52 = 344,52 cm
