Step-by-step explanation:

Step 1 of 5

Consider the function;

It means that the function is measured in terms of radius. The inverse of function is supposing say which measures the function in terms of circumference. The inverse of function is obtained by dividing the circumference by  as in the original function the function is multiplied by. So the inverse of function obtained is
