What is the sum of radii?
2 radii = one diameter
How do I find if 2 D shapes are similar?
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.
How many radii of a circle will equal its circumference?
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.
What is the difference between a Venn diagram with 2 circles and one with 3 circles?
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.
How do you create three different drawings showing a number of circles and triangles in which the ratio of circles to triangles is 2 3?
For each drawing . . .-- Draw a small number of circles.-- Draw that same number of circles again.-- Draw that same number of triangles three times.To create a different drawing, do exactly the same thing,but start out with a different small number.
What are 2 or more circles with the same center called?
concentric circles
What is the relationship between area of a circle and its radius squared for a series of circles with large increasingly large radii?
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
What are 2 circles drawn next to each other with the same radius called?
eyeballs
What is the ratio of the circumferences of two wheels if the ratio of their radii is 2 to 3?
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
Can 2 circles be congruent?
2 circles can be congruent. The have to have the same radius.
How do you draw 2 congruent ellipses?
draw 2 circles the same size
What is the sum of radii?
2 radii = one diameter
What is the area between 2 concentric circles called?
Annulus
Can you use a square and 2 circles to make up a cylinder?
Yes. Provided that the sides of the square are the same as the circumference of the circles.
How do you master the Etch a Sketch?
There are 2 perfect circles in the same size as "knobs."
In what year was the moon called Proteus discovered?
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.
How do I find if 2 D shapes are similar?
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.
