Create a C function called torus_volume which will have two input parameters-inner (a) and outer (b) radius. The function will calculate the volume of the torus which is given by the following equation:
V = pi pi'(a + b)(a - b)' (a - b)

Now, write a main program which will ask the user to enter the inner radius. The outer radius is calculated as two times larger than the inner radius. This program then will call the torus volume function from the main function to calculate the volume of the torus and print the result inside the main program.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
