Answer:
is the common ratio
Step-by-step explanation:
Common ratio(r) states that the ratio of each term of a geometric sequence to the term preceding it.
Given the sequence:
225, 45, 9, .........
Here,
and so on...
Using definition to find r.
After solving we get;
Therefore, the common ratio is,
10 because radius is half, so 5x2= 10
Answer:
41 units
Step-by-step explanation:
Rectangles have right angles, so we can use Pythagorean theorem to find the diagonal.
c² = a² + b²
c² = 9² + 40²
c² = 81 + 1600
c² = 1681
c = 41
It is 180 because it rotates
