(Geometry: area of a pentagon) Write a program that prompts the user to ente the length from the center of a pentagon to a vertex and computes the area of the pentagon, as shown in the following figure. 5 x The formula for computing the area of a pentagon is Area = where 4tan s is the length of a side. The side can be computed using the formulas= 2r sin where r is the length from the center of a pentagon to a vertex. Round up two digits after the decimal point. Here is a sample run: Enter the length from the center to a vertex: 5.5 The area of the pentagon is 71.92
