A = πr² + πrl
306.00 = 3.14(6)² + 3.14(6)(l)
306.00 = 3.14(36) + 3.14(6l)
306.00 = 113.04 + 18.84l
- 113.04 - 113.04
192.96 = 18.84l
18.84 18.84
10.24 ≈ l

Answer:
Step-by-step explanation:
The formula for a geometric sequence is where is the th term of the sequence, is the first term, and is the common ratio.
Since each term is being multiplied by 3, this is our common ratio.
Therefore, our geometric sequence formula is
