The radius of a circleis part of the circumference formula: C = 2 pi r.
So we rearrange the formula: r = c/2 pi.
Now we have to figure out the circumference. If the outside of the circle is 12 cm for 17degrees, then17 degrees x what is 360 degrees? 360 divided by 17 is 21.2. So the 12 cm should be multiplied by 21.2, to give 254.1cm. This is our circumference.
Now we do r = 254/2 pi.
r = 40.46cm.

Answer:
$11,991.60
Step-by-step explanation:
An appropriate formula is ...
A = P(1 +r/n)^(nt)
where r is the annual rate, n is the number of time per year interest is compounded, and t is the number of year. P is the principal invested.
Filling in the given numbers, we have ...
A = $2000(1 +0.12/12)^(12·15) = $2000(1.01^180) ≈ $11,991.60
The account balance after 15 years will be $11,991.60.
