We assume that the function is as follows:

Then, we have that:

Thus, if we have that:

Therefore, the value for the function is f^-1(2) = -1/2 or
Step-by-step explanation:
Circumference
C = 3.14x3
C = 9.42cm
Area
A = 3.14xr²
A = 3.14x25
A = 78.5ft
3/5 x 10= 6 miles because coach runs 10 times what you run
