Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. DII 3.2 (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- tagon, as shown in the following figure. 3√3 2 The formula for computing the area of a pentagon is Area -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5 = where r is the length from the center of a pentagon to a vertex. Here is a sample run:
