    The height of the carton of oatmoatmeal is 9 inches.

    Step-by-step explanation:

    Radius = 4 inches

    Area of cardboard used = 276 square inches

    Required surface area = π(r x r) + 2πrh

    276 = π(4 x 4) + 2π(4 x h)

    276 = 16π + 8π(h)

    276 = 50.24 + 25.12(h)

    276 – 50.24 = 25.12(h)

    225.76 = 25.12(h)

    (225.76) /(25.12) = h

    h = 9 inches

    The height of the carton of oatmoatmeal is 9 inches.
