There is a unique circle for three such points in the plane. or perhaps: That circle, rotated, gives the equation of the dome. So now you have the dome  you proceed to calculate the surface area. (If you know calculus, you can also calculate the surface area of revolution from the crosssection circle). Walter Whiteley
