    Answer:

    • Circumference = 69.14cm
    • Area = 380.29cm²

    Step-by-step explanation:

    Circumference.

    Circumference of a circle is calculated by the formula:

    = Pie * diameter

    = π * diameter

    = 22/7 * 22

    = 69.14 cm

    Area

    Area of circle:

    = Pie * radius ²

    Radius = diameter/2

    = 22/2

    = 11 cm

    Area = 22/7 * 11²

    = 22/7 * 121

    = 380.29 cm²
