Answer:
12.56 feet
Step-by-step explanation:
The perimeter of a shape is the sum of all its side.
Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".
The circumference of a circle has the formula:
Where
C is the circumference (perimeter of a circle)
r is the radius
Given,
r = 2 feet
We substitute and find the circumference, using 3.14 as 
,
Hence, the circumference is 12.56 feet

Answer:
Step-by-step explanation:
Compounding interest :
Future value of money = Present value * (1+ r)^N
r - interest rate
n - number of period
In our example, Present value = 325.76, FV = 400, r = 2%, and we need to find N
by solving that we can find it that N is equal to 10.3675
Simple interest :
400 - 325.76 = 74.26$ we need to increase
325.76*2% = 6.5152$ each year
74.26 / 6.5152 = 11.3949
as a whole year = 12years
