need help writing this program in c++

this how the program should execute

Lab Write a complete program that: 1. Creates a global constant to hold pi (1 - 3.141592). 2. Prompts the user to enter an angle in degrees then reads in an angle in degrees from the keyboard as a double. 3. Converts the angle from (2) to radians. 4. Computes the sine of the angle from (3) using $5.\; Computes\; the\; cosine\; of\; the\; angle\; from\; (3)\; using6.\; Computes\; the\; tangent\; of\; the\; angle\; from\; (3)\; using7\; Writes\; the\; answers\; from\; (3)\; (4)\; (5)\; and\; (6)\; out\; to\; the\; display.\; The\; formula\; to\; convert\; degrees\; to\; radians\; is:\; degreespi\; radians\; =\; 180\; The\; prototypes\; for\; sin()\; and\; cos)\; are:\; 1.\; double\; sin\; (double\; x);\; 2.\; double\; cos\; (double\; x);\; 3.\; double\; tan\; (double\; x);\; Enter\; an\; angle\; value,\; in\; degrees\; **10\; 10\; degrees\; =\; 0.174533\; radians\; sin(10)\; =\; 0.173648\; cos\; (10)\; =\; 0.984808\; tan\; (10)\; -\; 0.176327$
