Answer:
36
Step-by-step explanation:
because multiples of 12 are 12, 24, 36, 48, etc
multiplex of 9 are 9, 18, 27, 36, etc
you would stop at 36 becomes the smallest common multiple of both of them is 36 and there is your answer
<span>1520.5</span>^2 feet is the answer
Step-by-step explanation:

Answer:
circumference row- 18.85, 50.27, 175.93, 561.09
area row- 28.27, 201.06, 2,463.01, 25,052.6
You can try to show this by induction:
• According to the given closed form, we have
, which agrees with the initial value <em>S</em>₁ = 1.
• Assume the closed form is correct for all <em>n</em> up to <em>n</em> = <em>k</em>. In particular, we assume

and

We want to then use this assumption to show the closed form is correct for <em>n</em> = <em>k</em> + 1, or

From the given recurrence, we know

so that






which is what we needed. QED
