Hi Sravya, Here is a method to get started. Think of the height and the diameter (double the radius) as giving 3 points in the plane. 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 cross-section circle). Walter Whiteley | ||||||||||||
