They are congruent circles
2 radii = one diameter
The circumference of Circle K is ( \pi ), which implies its radius ( r_K ) is ( \frac{1}{2} ). For Circle L, with a circumference of ( 4\pi ), its radius ( r_L ) is ( 2 ). The ratio of their radii is ( \frac{r_K}{r_L} = \frac{1/2}{2} = \frac{1}{4} ). The areas of the circles are proportional to the squares of their radii, so the ratio of their areas is ( \frac{(r_K)^2}{(r_L)^2} = \frac{(1/2)^2}{(2)^2} = \frac{1/4}{4} = \frac{1}{16} ).
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
A venn diagram with 2 circles is comparing and contrasting two things while a venn diagram with three circles is comparing and contrasting two things to the same one subject instead of with each other.
concentric circles
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
eyeballs
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
2 circles can be congruent. The have to have the same radius.
draw 2 circles the same size
2 radii = one diameter
Annulus
Yes. Provided that the sides of the square are the same as the circumference of the circles.
There are 2 perfect circles in the same size as "knobs."
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
In what year was the moon called Proteus discovered? real answer is..... Answer: Discovered by Voyager 2 spacecraft in 1989, it is named after Proteus, the shape-changing sea god of Greek mythology. Proteus circles Neptune in a nearly equatorial orbit at the distance of about 4.75 equatorial radii of the planet.
