    The perimeter of a circle is also known as its circumference

    Since this is a semi-circle (or half a circle) you will either need to take half of the initial circumference you get, or do it in another complicated way. You'd get the same answer. Is this clear?

    You could also just do pie times radius so you wouldn't have to divide the circumference.
