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
Why was pi invented?
because its used to calculate areas of circle, circumferences and so on
What is the ratio of the circumferences for two circles with areas 6 pi m2 and 150 pi m2?
area = 2pi*r2circumference = 2pi*rThe ratio of their circumferences will be 2pi*r1 /2pi*r2 = r1/r21) r2 = 6pi/2pi = 3. r1 = root(3).2) r = 150pi/2pi = 75. r2 = root(75)So the ratio of their circumferences isr1/r2 = root(3)/root(75)
What is the ratio of the circumferences radii and areas of two circles with circumferences of π and 4π?
Ratio of circumference is π : 4π = 1 : 4 This is the ratio of all lengths, therefore their radii are in the ratio of 1:4 also. Ratio of areas is the square of the ratio of length → ratio of their areas is 1² : 4² = 1 : 16
What is a two sided shape called?
A diagon, is an example of a two sided shape, which is basically a secton of a sphere emcompassed by two circumferences disecting. or a plane (e.g a sheet of paper) or a strip (a simple ring shape)
Which lines are complete circles?

How do you do the circumferences and the diameters?
The answers depend on what you want to "do" and what information you have.
What are the inner and outer rims of a circle called?

If the diameter of a circle is 30Cm What is the circumferences?
d = 9.55 cm
How many circumferences has a circle?
Only one.
How do you find the circumferences of 10ft?
First you times 3.14 by the diameter and there you go
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
Why was pi invented?
because its used to calculate areas of circle, circumferences and so on
