Answer:
Using the attached formula:
exp = log (total/principal) / n * years
exp = log (10,000 / 7,500) / 12 * 20
exp = log (1.3333333333) / 240
exp = 0.1249387366 / 240
exp = 0.000520578069166667
rate = (10^exp -1) * n
rate = (10^0.000520578069166667 -1) * n
rate = 1.00119939400018 -1 * n
rate = .00119939400018 * 12
rate = 0.014392728
OR rate = 1.4392728 % Compounded Monthly
OR rate = 1.448805264762% Compounded Annually

Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20 = 62.831 in
