WebA surface of revolution is a surface in Euclidean space created by rotating a curve (the generatrix) around an axis of rotation.. Examples of surfaces of revolution generated by a straight line are cylindrical and conical surfaces depending on whether or not the line is parallel to the axis. A circle that is rotated around any diameter generates a sphere of … WebTherefore, The Curved Surface Area of Hemisphere =1/2 × 4 × πr 2. Curved surface area of a hemisphere = 2πr 2 . Since a sphere is a combination of a curved surface and a flat base, to find the total surface area we need to sum up both the areas. The flat base being a plane circle has an area πr 2.
