    Question:-

    The diameter of a circle is 18 m. Find its circumference in terms of π.

    Solution:-

    Diameter of a circle = 18 m. (Given)

    Radius (r) of a circle = 18/2 = 9 m.

    We know,

    \dag Circumference of a circle is 2πr.

    So, It’s circumference is (2 × π × 9) m.

    It’s circumference is 18π m.

    It’s circumference in terms of π is 18π m. [Answer]
