    Step by step explanation:

    The question is incomplete without the diagram of the shape or its dimensions.

    From the question, we are to determine the perimeter of the circle.

    Let's consider the following question by determining the perimeter of a circle. If diameter is 7cm. Use pi as 3.14.

    Perimeter of circle = circumference of circle

    circumference of circle = 2πr

    Radius = diameter/2 = (7/2) cm

    circumference of circle = 2πr

    = 2*π * (7/2) = (14/2) * 3.14

    = 7*3.14

    =21.98cm

    circumference of circle = 22cm (nearest tenth)

    Perimeter of circle = 22cm
