Question

Suppose you know that on the xy-plane, the diameter of the circle is goes from one coordinate (x1,y1) to another (x2, y2). How do we get the radius? And what would be the equation of this circle?

Answer 1

Do we find the midpoint of the coordinates?

Answer 3

@mahmit2012 more specifically, the question is this:

In all of this question C represents the curve y = e^x
where x ∈ [0, 1]

(a) [5 points] Find the function A(x) that gives the area of the circle whose diameter
has one endpoint (x, y) on C and the other endpoint at (1, 0)
