what do i do with that ^4?
1st question is that the right formula?
Answers:Taking this question and breaking it down  The formula  Perimeter of a full circle is 2 * pi * r or pi * diameter for a semicircle or half of a circle you need to also add a diameter for the line that connects the open circle .... so, In the form that you can use r in the calculation : (( 2 r ) / 2 ) + 2 r or r + 2 r or r ( +2) For your answer r = 4 4 ( 3.14 + 2) = 20.56 inches I hope this helps.

Question:Hi, I am in Maths and my teacher has asked me to find the perimeter of a semicircle. I need the formula so please help! (No stupid answers please :l)
Answers:The circumference of a circle is given by the formula: C = 2 r where r is the radius of the circle. A semicircle would be onehalf of the full circumference ! We usually call the distance around a circle the circumference rather than the perimeter. QED
