A slice made by a chord that spans the sector is called a segment, as shown in the right figure of the above diagram. You will write two functions to com and the segment. pute the areas of the sector 8. Write a function prototype and then its implementation called sector_area), computes the area of the entire sector. The function has two parameters: the radius r of the and the angle e (in radians) both of type double. The function returns the area of the sector whose value is of type double. The formula to compute the area of the sector is: 9. Write a function prototype and then its implementation called segment_area), which computes the area of the segment of the sector. The function has two parameters: the radius r of the circle and the angle e (in radians) both of type double. The function returns the area of the segment whose value is of type double. The formula to compute the area of the segment is: area = (9-sin(6)) 10. Thoroughly test your code. Initially use a radius of 1 and try different values for angle e, which must be expressed in radians! You are probably more familiar with angles expressed in degrees. Remember that 90 degrees /2 radians1.571 and 180 degrees n radians 3.142. Try your program using these radian values along with m/4 radians (45 degrees), 37/4 radians (135 degrees), ST/4 radians (225 degrees), and other radian values. Try different radius values other than 1.
