36) ( - 3.500) ÷ ( -50) + 20 × ( - 350) + 700
= 70 + ( - 7.000 ) + 700
= ( - 6.930 ) + 700
= ( - 6.230)
37) r = ³√V
r = ³√15.625
r = 25 dm
38) w = 15 mnt
d = 250 dm³/mnt
volume = w × d
= 15 mnt × 250 dm³/mnt
= 3.750 dm³
= 3.750 ÷ 1.000
= 3,75 m³
39) d = 21 cm
r = 21 ÷ 2 = 10,5 cm
t = 100 cm
V = π × r² × t
= 22/7 × 10,5 × 10,5 × 100
= 34.650 cm³
40) bikin diagram sendiri ya dek ;)
