    The units are always squared.

    The area can be found when given the diameter by first finding the radius.

    Circumference can be used to find area.

    Step-by-step explanation:

    1) The diameter is NOT used in the formula. The formula is

    Area = pi * radius * radius

    2) The units are always squared. Units for area are always squared.

    3) The area can be found when given the diameter by first finding the radius.

    Diameter/2 = radius, which is the only missing part we need to find the area.

    4) The area is NOT the distance around the circle. That is the circumference. Area is contained within the circle.

    5) Circumference can be used to find area.

    Circumference/pi = diameter, and with the diameter, we can find the area as explained in 3
