Practice Problem: Find the area and circumference of a circle with a diameter of 4 inches. Solution: One of the first rules of solving these types of problems involving circles is to carefully note whether we are dealing with the radius or the diameter. In this problem, the circle is described using the diameter, which is 4 inches. The radius.
This paper identifies a specific contents-based strategy for problem solving based on analytical geometry procedures. Here, an appropriate methodology for putting the strategy into practice, will.
