Answer:
Step-by-step explanation:
To find the inverse of the function , the first step is to replace f(x) with "y":
The second step is to solve for the variable "x":
The third step is to interchange the variables, then:
Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:
V= 
r^2h
V= 3.14*5^2*7
V= 3.14*25*7
V= 3.14*175
V= 549.5 cm squared
V= 3.14*5^2*7
V= 3.14*25*7
V= 3.14*175
V= 549.5 cm squared
