Answer:
Step-by-step explanation:
if we need to approximate,
the radius=125, the diameter is d=250
we estimate that pi=3
C=3*250=aprox 750
the closest number is 785

As we know that :
so, over here
plugging the value of i² as -1
Answer:
Substitute your answer for Step 1 into the second equation to solve for Z.
Return rate, r = 3% = 0.03
x = initial investment
b = final balance
After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x
Because r = 0.03,
b = 1.03x (after 1 year)
