    C = 6.28 A: 3.14

    Step-by-step explanation:

    Circumference of a circle is 2 * pi * r

    Based on this, we can subsitute r for 1

    2 * pi * 1 = 2pi which is around 6.28 units

    Area of a circle is pi * r * r

    Based on this, we can subsitute r for 1

    pi * 1 * 1 = pi = 3.14 units squared
