Answer:
it is the question, c=2PIr
Step-by-step explanation:
Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form:
....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function: 
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
285$ divided by 5$ = 57, 57 would be the correct answer.
The answer to this question is true
