9. V = alas × tinggi ÷ 2 × tinggi prisma = 6cm × 5cm ÷ 2 × 8cm = 3cm × 5cm × 8cm = 15cm² × 8cm = 120cm³ ⇒ (c) 10. V = π × rusuk × rusuk × tinggi = 22/7 × 14cm ( dijadikan jari-jari aja ) × 14cm × 8cm = 22/1 × 2cm × 14cm × 8cm = 44cm × 14cm × 8cm = 616cm² × 8cm = 4.928cm³ ⇒ (a)
= ( a x t )/2 x 8
= (5cm x 6cm)/2 x 8cm
= 30cm²/2 x 8cm
= 15cm² x 8cm
= 120cm³ (C)
10. diameter = 28cm
jari jari (r) =14cm
tinggi = 8cm
volume tabung = πr²t
= 22/7·14cm·14cm·8cm
= 22·2cm·14cm·8cm
= 22·224cm³
= 4928cm³(A)
= 6cm × 5cm ÷ 2 × 8cm
= 3cm × 5cm × 8cm
= 15cm² × 8cm
= 120cm³ ⇒ (c)
10. V = π × rusuk × rusuk × tinggi
= 22/7 × 14cm ( dijadikan jari-jari aja ) × 14cm × 8cm
= 22/1 × 2cm × 14cm × 8cm
= 44cm × 14cm × 8cm
= 616cm² × 8cm
= 4.928cm³ ⇒ (a)
Maaf kalau salah dan semoga bermanfaat
