In Programming 18–P1, you were asked to write the assembly language procedure (favg) as a separate module. Rewrite this function in inline assembly.

Write a mixed-mode program that reads the radius (r) of a circle and computes its area.

The main procedure (written in C) handles the user interface. It reads the radius (as

a double) and passes it to the assembly language procedure farea. This procedure

computes the area (πr2

) and returns it to the main procedure. The main procedure prints

the area.
