What is the area of a circle with a diameter of 36 millimeters?

1 Answer

  • Answer:

    ≈1,017.36 or in terms of pi: π324

    Step-by-step explanation:

    Formula for area of a circle: π * r ²

    r = half of the diameter

    Diameter is 36, divide it by 2, radius is 18.

    Apply the formula:

    π * 18²

    π * 324

    If pi is rounded to 3.14:

    3.14 * 324 = 1,017.36
