    Step-by-step explanation:

    Radius (r) = 7 feet

    circumference (c) = ?

    We know

    C =2 πr

    = 2 * 3.14 * 7

    = 43.96 feet

    Hope it will help 🙂

    Answer:  43.96

    ==================================================

    Work Shown:

    C = 2*pi*r

    C = 2*pi*7

    C = 2*7*pi

    C = 14pi …………. exact circumference in terms of pi

    C = 14*3.14

    C = 43.96

    This value is approximate because pi = 3.14 is approximate.

    Note: the circumference is the same as the perimeter of the circle. It’s the distance around the circle’s edge.
