A circle has a diameter of 4 m.

What is the best approximation of its area?

Use 3.14 to approximate for π.

6.28 m²

12.56 m²

25.12 m²

50.24 m²

I think it's 12.56 m^2 but I'm not exact

    A = π r ²

    Take half of the diameter for the radius, so the radius is 2m

    A=π 2 ²

    A = 12.57 m²

    So, yes, you are correct
