dit: r:7cm t:10cm vi 22/7 carilah volume dan luas tabung

2 Jawaban

  • Volume Tabung :
    V = πr²t
    V = 22/7 × 7 × 7 × 10
    V = 22 × 7 × 10
    V = 154 × 10
    V = 1.540 cm³

    Luas Permukaan Tabung :
    L = 2πr(r + t)
    L = 2 × 22/7 × 7 × (7 + 10)
    L = 2 × 22 × 17
    L = 44 × 17
    L = 748 cm²

    Maaf Kalau Salah
  • V = [tex]/pi×r×r×t
    = 3,14×7×7×10
    = 15.386×10
    = 153.860cm
