Answer:
pls mark me as brainliest
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
3
gives the next term. In other words,
a
n
=
a
1
⋅
r
n
−
1
.
Geometric Sequence:
r
=
3
This is the form of a geometric sequence.

Answer:
Diameter = 14 cm
Circumference = 44 cm
Step-by-step explanation:
- Area of circle = πr²
- Diameter = 2r
- Circumference = 2πr = πd
- π ≈ 3.142
