3.I (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- in the following figure. 36 Chapter 3 Mathematical Functions, Strings, and Objects 3V3 The formula for computing the area of a pentagon is Area = the length of a side. The side can be computed using the formula s = 2r sin- where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5ter The area of the pentagon is 108.61
