tolong jawab ayu ini buat pr besok kalo aku dihukum

6.
r = D ÷ 2 = 28 cm ÷ 2 = 14 cm

L = πr²
L = 22/7 × 7 × 7
L = 22 × 7
L = 154 cm²

Jawaban : A. 154 cm²

7.
L = πr²
L = 3,14 × 10 × 10
L = 314 cm²

Jawaban : C. 314 cm²

8.
r = D ÷ 2 = 20 cm ÷ 2 = 10 cm

L = ½ πr²
L = ½ × 3,14 × 10 × 10
L = ½ × 314
L = 157 cm²

Jawaban : B. 157 cm²

9.
V = πr²t
V = 22/7 × 14 × 14 × 20
V = 22 × 2 × 14 × 20
V = 44 × 280
V = 12.320 cm³

Jawaban : D. 12.320 cm³

10.
V = ½ × a × t × T
V = ½ × 16 × 12 × 40
V = 8 × 12 × 40
V = 96 × 40
V = 3.840 cm³

Jawaban : A. 3.840 cm³

Maaf Kalau Salah
