Question 728457: Find the perimeter of a 60 degree slice of a small 5 inch radius pizza.
I made the mistake of using the formula (60)/(360)pi r squared and got 13.09 to try and find the perimeter.. and then I realized that that is how you find the area and not the perimeter. I have no idea how to find the perimeter. Please help me? Thank you!

-------------------
Use the same method.
The whole perimeter = 2*pi*r = 10pi inches
(60/360)*10pi = 5pi/3 inches
=~ 5.236 inches
