Hey there!
A common ratio is just that number that you multiply or divide to each number that gets you the next in a geometric sequence. In this sequence, we know the numbers are getting bigger and we're multiplying, so we want to know what you're multiplying by the first number to get to the second. We can call this unknown number x. SO if we start with the first number and set up an equation, we get:
3x = 12
Divide both sides by 3
x = 4
Therefore, your common ratio is 4.
To check, you can multiply all the next numbers by 4 to see that it all checks out.
Hope this helps!
Answer:
864
Step-by-step explanation:
because if you take 8 percent of 900 72 x 12 you get 864.
To find the circumference (c) use the formula (pi d) in other words 3.14 x diameter
To find the radius to find the diameter: 2R (double the radius)
To find radius 1/2 D (half the diameter)
An acute angle is infact 90 degrees, therefore your answer is correct.
