1 It's a perfectly rounded 2 dimensional shape
2 It can be easily constructed with a pair of compasses
3 Its perimeter is better known as its circumference
4 Its radius is half of its diameter
5 Its diameter spans its circumference cutting through its centre
6 It can be concentric with other circles sharing the same centre
7 Its circumference divided by its diameter is the value of pi
8 Its pi value has never been finally determined because it's an irrational number
9 Its area is: pi*radius squared
10 Its circumference is: 2*pi*radius or diameter*pi
11 Its radius can be found by: circumference/2*pi
12 Its diameter can be found can be found by: circumference/pi
13 Its circumference touches a tangent line at only one point
14 Its circumference is a full rotation of 360 degrees
15 Its circumference measured in parts are arcs
16 Its radius is the same circular length of an arc which is a radian
17 Its radian is about 57.3 degrees
18 Its lines of symmetry are infinite
19 It has chords which are straight lines spanning its circumference
20 It has sectors which is an area enclosed by an arc and 2 radii
21 It has segments which is an area enclosed by an arc and a chord
22 Its shortest distance from its centre to its circumference is via its radius
23 It forms the base of a cone
24 It forms the parallel bases of a cylinder
25 Its best friend is the sphere because they have so much in common
They can be: a sector, a segment and a tangent
The least common multiple of four, twenty eight, and twenty is 140.
five
The LCM is: 264
number one is the second number, it come before 2 and after 0, it only had lines, it doesn't have any curves sorry thats all i got
at least twenty
You have it at least for twenty days
80
100
812 is the LCMIt is: 812 and any of its multiples
No
a circle, which has none
