  • 4. L1 = phi × r^2

    = 22/7 × 7^2

    = 22/7 × 49

    = 22 × 7

    = 154


    L2 = p × l

    = 25 × 14

    = 350


    Luas gabungan = L1 + L2

    = 154 + 350

    = 504 (b)



    5. V = phi × r^2 × t

    = 22/7 × 14^2 × 20

    = 22/7 × 196 × 20

    = 22 × 28 × 20

    = 12.320 (a)
