    Question:-

    If the diameter of the circle above is 16 mm, what is the area of the circle ?

    Solution:-

    Diameter of the circle = 16 mm. (Given)

    Radius (r) of the circle = 16/2 = 8 mm.

     \bigstar To Find the area of the circle.

    Since we know,

     \dag Area of circle is πr².

    So, Area of the circle = 3.14 × (8)²

    Area of the circle = 3.14 × 8 × 8

    Area of the circle = 200.96 = 201 mm².

    The area of the circle is 201 mm². [Answer]

    Answer:

    64\pi mm² or approximately 201.06 mm²

    Step-by-step explanation:

    If the diameter is 16 mm, the radius will be 8 mm.

    Use the circle area formula, A = \pir², where r is the radius. Plug in 8 as r:

    A = \pi

    A = \pi(8²)

    A = 64\pi

    So, the area of the circle is 64\pi mm² or approximately 201.06 mm²
