(mentor note: posted in a non-homework forum hence no template) Hello! I have a problem i'm trying to solve. I'm transforming a circle with known radius. Knowing it's radius i can calculate the circumference. I transform it by squeezing one side, leveling it, creating a circle segment with a measurable height and the same perimeter as prior circle circumference. Is there any way to calculate the segments circles radius? Imagine you can't measure the chorde. All i'm given is height and perimeter.
