25) d = v ÷ w
= 200 m³ ÷ 5 mnt
= 40 m³/mnt

26) L = ½ × d1 × d2
450 = ½ × 15 × d2
450 × 2 = 15 × d2
900 = 15 × d2
d2 = 900 ÷ 15
d2 = 60 cm

27) L = π × r²
154 = 22/7 × r²
154 × 7 = 22 × r²
1078 = 22 × r²
r² = 1078 ÷ 22
r = √49
r = 7 cm

28) L½ = ½ × π × r²
157 = ½ × 3,14 × r²
157 = 1,57 × r²
r² = 157 ÷ 1,57
r = √100
r = 10 cm

29) V = π × r² × t
4.620 = 22/7 × 7 × 7 × t
4.620 = 154 × t
t = 4.620 ÷ 154
t = 30 cm

30) urutan data
6 , 7 , 7 , 8, 8 , 10
median
= ( 7 + 8 ) / 2
= 15 / 2
= 7,5
