$\huge\underline\bold\red{AnswEr}$

→The circumference of a circle is defined as the linear distance around it. In other words, if a circle is opened to form a straight line then the length of that line will be the circle's circumference

→Perimeter is the total length of the sides of a two-dimensional shape. We often find the perimeter when putting up Christmas lights around the house or fencing the backyard garden.
