Answer:
I think it's 500
Step-by-step explanation:
Since each decagon is 10 Units of perimeter each 50 Decagons (50*10) is 500
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
1. A= 3.14(8 cubed)
A=200.96
A=201
I think this is the answer rounded to the nearest tenth! Hope this helped!
