    A≈28.27cm² is the area of the circle with diameter 6cm

    as

    Area of a circle = pi * r²

    Since the diameter is twice the radius, the radius is 6cm/2 which is 3cm.

    pi * 3 * 3

    = 28.2743339cm²

    Area of circle = πd²/4, where d = diameter

    = π*6*6/4 = 9π ≈ 9 * 3.1416 ≈ 28.2744 cm²

    Area ≈ 28.27 cm²

    Hope this explains it.
