Develop a C program that interacts with the user by requesting two pieces of information: the diameter

of a circle and their preferred value for pi$.$ For this program, use the constant value of pi as $3\mathrm{.}1416.$

Task $2$: After obtaining the user's input, your program should perform the following calculations and display

the results:

a$)$ Calculate and display the radius of the circle, showing it with precisely $4$ decimal places.

b$)$ Calculate and display the diameter of the circle, presenting it with $3$ decimal places.

c$)$ Calculate and display the circumference of the circle, representing it in scientific notation with exactly $2$

decimal places.

d$)$ Calculate and display the area of the circle, showing it with one decimal place
