Detailed explanation-1: -When looking at a diagram of a spiral model, the radius of the spiral represents the cost of the project and the angular degree represents the progress made in the current phase.
Detailed explanation-2: -Which statement is true about the Spiral model? It is a hybrid approach that uses both Waterfall and iterative approaches.
Detailed explanation-3: -Explanation: The radial dimension of the model represents the cumulative costs and the angular dimension represents the progress made in completing each cycle. Each loop of the spiral from X-axis clockwise through 360o represents one phase.
Detailed explanation-4: -The exact number of loops in the spiral is not fixed. Each loop of the spiral represents a phase of the software process. The following activities are carried out during each phase of a spiral model. During the first quadrant, it is needed to identify the objectives of the phase.
