# What are the equations to find a segment and sector of a circle?

I also forget which is which. Is the segment the "pizza slice" looking part and the sector the "crust".

um your question is a bit confusing. If the sector is the area of the space from the angle to the segment of the curcumference. Use (x/360) = (y/2 pi r) as a proportion , with x being the degrees of the central angle and y being the section of the curcumference. I have never heard of the pizza slice and crust reference which is what made it confusing. But basically just put part to whole over part to whole as a proportion
