Answer:
C = 2 π r
Step-by-step explanation:
Your answer is 2 pi/π r.
The formula of a circumference is always 2 pi r.
18 x 3.14 x 2 = 113.04
in this case radius is 18
pi is 3.14
2 is just always there when finding out circumference.

Answer: a1 = 3 and r = 2
Step-by-step explanation:
A geometric progression, also called a geometric sequence, is a sequence of numbers whereby every term after the first is gotten by multiplying the previous one by a fixed and non-zero number that is called the common ratio.
In this geometric progression, a5= 48 and a11= 3,072. To get the first term and the common ratio has been attached.
Answer:
140
Step-by-step explanation:
You answer should be B because you would flip the fraction so the powers would become positive and then take 3 from 5 to be left with 8^2 on the bottom with one on the top.
