The constant is the height over width
We know that the true value for pi is given as 3.14156.
Now, we have been given that the approximate value for pi is 3.141
We know the formula
Absolute error, 
Relative error is given by
![\text{Relative error }= \frac{\Delta x}{\text{true value} }\\ \\ \text{Relative error }=\frac{0.00056}{3.14156} \\ \\ [tex]\text{Relative error }=0.000178](https://tex.z-dn.net/?f=%5Ctext%7BRelative%20error%20%7D%3D%20%5Cfrac%7B%5CDelta%20x%7D%7B%5Ctext%7Btrue%20value%7D%20%7D%5C%5C%0A%5C%5C%0A%5Ctext%7BRelative%20error%20%7D%3D%5Cfrac%7B0.00056%7D%7B3.14156%7D%20%5C%5C%0A%5C%5C%0A%5Btex%5D%5Ctext%7BRelative%20error%20%7D%3D0.000178)

Answer:
Where's the answer?
Step-by-step explanation:
Answer:
In 4 years = $1,893.72
In 16 years = $3,810.53
years to contain $2,000 = 4.9371454128
years to contain $2,500 = 8.766692911
Step-by-step explanation:
In 4 years
A = 1,500 (1 + 0.06)^4
= $1,893.72
In 16 years
A = 1,500 (1 + 0.06)^16
= $3, 810.53
to find number of years
t = ln (A/P) / ln (1+r)
when A = 2,000
t = ln(2,000/1,500) / ln(1+0.06)
= 4.9371454128 years
when A = 2,500
t = ln(2,500/1,500) / ln(1+0.06)
= 8.766692911 years
PS: You can also use log in place of ln
