    Lateral area of the cone = 15 π sq. cm

    Step-by-step explanation:

    Lateral area of the cone A = πr √ (h² + r²)

    Here h = 4 cm and r = 3 cm

    Plugin the values we will get the lateral area as,

    A = π * 3 * √ (4² + 3²)

    = π * 3 * √ (16 + 9)

    = π * 3 * √ (25)

    = π * 3 * 5

    = 15 π sq. cm
