All circles are similar.
If they were congruent, they would have the same radius's/diameter's.
Circle B = diameter of 6
Circle A = radius of 4
Diameter = 2 * Radius
Circle A = diameter of 4 * 2 = 8
So they have different diameter's, therefore they are not congruent. So they are similar only.
(4 1/2) / (1 1/4)=9/2 / 5/4=9/2x4/5=18/5=3 3/5
= 3.6 buckets
or could have done 4.5/1.25
Answer:
<h2>-4</h2>
Step-by-step explanation:

Answer:
x - 8
Step-by-step explanation:
Plug in -1 for x and you get x - 8
The length of the circumference is (being

the diameter, and using 3.14 for

):

The perimeter of the hexagon is 12 cm.
Hence, the circumference is 0.56 cm longer than the perimeter of the hexagon.
