Answer:
C
Step-by-step explanation:
Hey There so the first step of this problem is to find the formula for circumference
given some of the values we can form an equation to solve for the radius (r)
so we can conclude that the radius is equal to 5
The perimeter of a square with sides 20 feet long would be 80.

Answer:
66
Step-by-step explanation:
The sequence you provided seems to be arithmetic as it increases as 4 each term. Assuming 1 is the first term the equation would be . You could just take the first 6 terms and add them together since you already have 4 values calculated and you could calculate the other 2 by adding 4. This would give you
(1 + 5 + 9 + 13 + 17 + 21) = 66
But there's an easier way to do it. You could use the formula . You can calculate by plugging in those values. You would need to calculate before hand, but you can calculate that using the formula I defined above. Which in general is where d is like the slope, or how much it changes each term. So if you calculate you'll get . Now plug this into the series formula above and you get which is exactly what you get if you add the first 6 terms as shown above when you do it manually.
