    Find the perimeter of the circle is the same as finding the circumference of the circle.

    Circumference Formula: C = 2πr

    Divide the diameter by 2 to find the radius.

    7 / 2 = 3.5

    Solve using the given values.

    C = 2 (3.14) (3.5)

    C = 2 (10.99)

    C = 21.98

    Therefore, the circumference (perimeter) of the circle is 21.98cm²

    Best of Luck!
