How do I code this to get the exact output like the sample run???

1. Calculate the area of a pentagon. Ask the user to enter the length from the center of a pentagon to a vertex, then compute the area of the pentagon. The formula for computing the area of a pentagon is: Area = Where s is the length of a side. The length of a side can be computed by using 3V3 2 2 the formula: s 2r sin Where r is the length from the center of the pentagon to a vertex. Format your answer to two decimal places. Here is a sample run: Enter the length from the center to a vertex: 5.5 The area of the pentagon is 108.61
