    Answer:

    Diameter: 12

    Circumference: 37.68

    Area: 113.04

    Step-by-step explanation:

    The radius of the circle is 6 cm.

    To find the diameter of a circle, multiply the radius by 2.

    6 × 2 = 12.

    12 is the diameter.

    —————————————————————————————————————-

    Formula for the circumference of a circle: πd (diameter).

    In other words, to find the circumference of a circle, multiply the diameter by pi.

    **3.14 IS A SUBSTITUTE FOR PI**

    12 × 3.14 = 37.68

    Therefore, 37.68 cm is the area of the circle.

    —————————————————————————————————————-

    Formula for area of a circle: πr² (r = radius).

    3.14 × 6 × 6 = 113.04

    Therefore, 113.04 cm² is the area of the circle.
