Circumference of a circle= πd = 10π
Divide by 2 and then add 10
Final answer= 25.7
A)

= 10 * 10 * 10 = 1,000
It is not A
B)

= 10 * 10 * 10 * 10 = 10,000
It is not B
C)

= 10 * 10 * 10 * 10 * 10 = 100,000
It could be C
D)

= 10 * 10 * 10 * 10 * 10 * 10 = 1,000,000
It is not D
Your answer is C)
Hope I helped!
Answer:
C, F, and H do not have solutions.
Step-by-step explanation:
1/16=a(1/4)^(5-1)
1/16=a(1/4)^4
1/16=a/256
256/16=a
16=a
So the initial term is 16 so our formula is:
a(n)=16(1/4)^(n-1)
