A definition of a common ration Is the number multiplied must be the same for each term in the sequence. The common ratio is the amount between each number in a geometric sequence. To determine the common ration you can just divide each number from the number preceding it in the sequence. Here is an example I found of a common ration to further help you
2,4,8,16
16/8=2 you would then continue to divide to ensure that the pattern is the same for each number
8/4=2
4/2=2 the ratio is the same for each one so the common ration would be 2 I hope this helps could I please get a brainliest :)
Answer:
given the circumference is 30t.
Step-by-step explanation:
The circumference of a circle is 
and the area of a circle is 
assuming the radius is 
for the circle in question.
We are given the circumference of our circle is 
.
If we solve this for r we get: 
. To get this I just divided both sides by 
since this was the thing being multiplied to .
So now the area is 
.
Simplifying this:
.
30/2=15 so:
.
Squaring the numerator and the denominator:
Using law of exponents or seeing that a factor of 
cancels:
It's 4:3 because if its 24:18 you can break it down by dividing 6 from both of them to get 4:3
Let me try my best if I can help you
