Detailed explanation-1: -Answer and Explanation: The spiral model has two dimensions namely c) radial and angular. The spiral model uses iterations with spirals.
Detailed explanation-2: -The activities in this model organized like a spiral that has many cycles. The radial dimension represents the cumulative cost incurred in accomplishing the steps done so far and angular dimension represents the progress made in completing each cycle of the spiral.
Detailed explanation-3: -At any point, the Radius of the spiral represents the expenses(cost) of the project so far, and the angular dimension represents the progress made so far in the current phase.
Detailed explanation-4: -The spiral model has four phases: Planning, Design, Construct and Evaluation.
Detailed explanation-5: -The spiral model, initially proposed by Boehm, is an evolutionary software process model that couples the iterative feature of prototyping with the controlled and systematic aspects of the linear sequential model. It implements the potential for rapid development of new versions of the software.
