No 36 1 ton = 1000 kg 4 1/2(4.5) ton = 4500 kg 1 kw = 100 kg 2.5 kw = 250 kg 1 ons = 0.1 kg 350 ons = 35 kg jadi. 4500kg+250kg+35kg= 4785 kg

36. 4 1/2 ton + 2,5 kw + 350 ons = n (4 1/2 x 1000) + (2,5 x 100 ) + (350/10) = n (9/2 x 1000) + (5/2 x 100) + 35 = n 4500 + 250 + 35 = n 4750 + 35 = 4785 kg
37.
38. 15m x 9m = 135m 30cm x 30cm = 900cm = 9m 135/9 = 15 keramik
39. diameter = 90m, r = 90/2 = 45 K = pi x d = 3,14 x 90 = 282,6 m L = pi x r² = 3,14 x 45² = 6358,5
1 ton = 1000 kg
4 1/2(4.5) ton = 4500 kg
1 kw = 100 kg
2.5 kw = 250 kg
1 ons = 0.1 kg
350 ons = 35 kg
jadi.
4500kg+250kg+35kg=
4785 kg
(4 1/2 x 1000) + (2,5 x 100 ) + (350/10) = n
(9/2 x 1000) + (5/2 x 100) + 35 = n
4500 + 250 + 35 = n
4750 + 35 = 4785 kg
