    Q 10
    (D) =14cm
    R = 14/2 = 7cm
    Label height= 20 - 4 = 16
    Area of label = 2πrh
    = 2 ❌ 22/7 ❌ 7 ❌ 16
    = 704 cm ²

    Q10:
    Height of cylinder = 20-(2+2)
    =20-4
    =16cm
    Diameter= 14 cm
    Radius=d/2
    =14/2
    =7cm
    Now, area of label = L.S.A of cylinder
    =2πrh
    =2 × 22/7 × 7 × 16
    =44 × 16
    = 704cm²

  • @Krish-i7q
    @Krish-i7q 3 роки тому +63

    Q10
    ans - Take the radius , first by dividing diameter/2 = 14/2 = 7cm
    Height = 20cm
    Since the height of Label is placed 2cm from top and bottom
    = 20 - (2+2) = 16 cm
    And now the lateral surface area =
    2 × pie × r × h
    = 2 × 22/7 × 7 × 16
    = 704 cm²

    Q10
    Radius =14/2= 7 cm
    height=(20-2-2)cm =20-4= 16cm
    curved surface area of label =2πrh
    =2×22/7×7×16 cm sq
    =704cm sq

    Here's question 10:-
    Base diameter of Label:-14cm
    -Radius=14/2=7cm
    Now,height of label=20-(2+2)
    -20-4
    =16cm
    Thus area of label =2πrh
    =2*22/7*16
    =704cm²
    (here "*" means multiply)

      10th solution:-
      Here, r = 14/2 = 7cm
      Height of cylindrical shaped label = 20 - (2 + 2)
      = 20 - 4
      = 16 cm
      L.S.A of the cylindrical shaped label = 2πrh
      = 2 × 22/ 7 × 7 × 16
      (7 and 7 cancel)
      = 2 × 22 × 16
      = 44 × 16
      = 704 cm²
