    Area of a circle in terms of radius:

    Area = π · r2 = 3.14 · 1.072 = 3.57 square meters.

    In terms of diameter:

    Area = π · (d

    2

    ) 2 = 3.14 · (2.13

    2

    ) 2 = 3.14 · (1.07) 2 = 3.57 square meters.

    In terms of circumference:

    Area = C2



    = 6.72



    = 44.89

    (4 · 3.14)

    = 44.89

    12.56

    = 3.57 square meters.

    Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.

    A circle of radius = 1.066 or diameter = 2.133 or circunference = 6.7 meters has an area of 3.572 square meters which is equal to:

    3.572E-6 square kilometers (km²)

    35720 square centimeters (cm²)

    0.0008827 acres (ac)

    0.0003572 hectares (ha)

    1.379E-6 square miles (mi²)

    4.272 square yards (yd²)

    38.45 square feet (ft²)

    D=2.133

    Step-by-step explanation:

    the circumference is to 2π • r where r is the radius, which is equal to half the diameter D so we have:

    6.7 = 2 • π • r

    r = d/2

    substituting the 2nd equation to the first gives:

    6.7 = 2 • π • d/2

    6.7 = π • d

    d = 6.7/π = 2.133
