<span>The principal is $1920.96 .
APR 18.6% .
Interest is compounded monthly .
Formula for compound interest is
A = P (1+r/t) ^n(1/t)
P = principal amount (the initial amount you borrow) which is $1920.96
r = annual rate of interest (as a decimal) = 0.186
t = period
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year = 12 times .
A = P (1+r/t) ^n(1/t)
A = 1920.96*(1+0.186/12)^12(1/12)
= 1920.96(1+1.0155)
= 1951.04

Answer:
2.195%
Step-by-step explanation:
Assuming that both planets are a sphere, we have to:
26590 * 28% = 7445.2
7445.2 miles would be the diameter of the moon, now to calculate the volume, we know that the radius is half the diameter, so:
r2 = d2 / 2 = 7445.2 / 2 = 3722.6
and the radius of the planet would be:
r1 = d1 / 2 = 26590/2 = 13295
now the volume of the planet we know is equal to:
v1 = 4/3 * pi * r1 ^ 3
and the volume of the moon would be:
v2 = 4/3 * pi * r2 ^ 3
We want to calculate the percentage by volume, therefore:
v2 / v1 = 4/3 * pi * r2 ^ 3 / 4/3 * pi * r1 ^ 3
v2 / v1 = 3722.6 ^ 3/13295 ^ 3
v2 / v1 = 0.021952
that is, the volume of the moon represents 2.195%
In number form it sounds like it would be 600,201,094
Common factors are 1,2,4 so the greatest one would be 4
