centimeter
centimetre m

Centimeter . A centimeter is one-hundredth of a meter.
The diameter of the penny in the picture above is 2 cm. It is written as follows: 2 cm.


center
center m

center . The center of a circle is the point at which all points on the circumference of the circle are equal. The distance between the center and any of the points on the circumference is called the radius.
The center of the sphere is the point at which it is equal from all points on the surface of the sphere. This distance is called the radius (radius) of the ball.


characteristic
partie f entière

True part. When using regular logarithms with base 10, the integer part of the logarithm is the integer part of the logarithm when written in the traditional way. The integer part contains information related to the location of the decimal point in the original number. For example:

4.1 x 0.041 - 10-2

log (0.041) = log (10-2 × 4.1)

= log (10-2) + log (4.1)

2 + 0.6128 - =

Who writes 2.6128
And 2 is the integer part of the logarithm.


chord
cord f

String . A straight line connecting two points on a curve.
Two examples of strings.


circle. circle
circle m

circle . A flat curve formed by the set of all points with a given fixed distance from a fixed point. The fixed point is called the center, and the fixed dimension is called the radius.

radius (radius)
center

The area of ​​a circle with radius R is equal to πR2, and its circumference is 2πR.
Circles have linear and rotational symmetry of infinite order around the center.
For a fixed perimeter, the circle encloses the maximum area compared to any flat curve.


circumference
circumference f

circumference of a circle . This term means the boundary line of the circle, the length of this line, or the distance surrounding the circle alike.

The ratio of the circumference of the circle to the diameter is constant for all circles and is symbolized by the Greek letter π (pi). From a numerical standpoint, π is an irrational number with an approximate value of 3.14 (rounded to three significant figures). Therefore, the circumference of a circle can be calculated using the formula Circumference = π × Diameter. For example: The circumference of a circle with a diameter of 6 cm = 3.14 x 6 cm (= 18.8 cm).


circumscribe
circonscrire

Surrounds. A circle is bounded by a polygon if all vertices of the polygon lie on the circumference of the circle.

The center of the circumference of a triangle is located at the intersection of the perpendicular bisectors of the sides of the triangle.

A polygon that has a circumscribed circle is called a cyclic polygon.


class interval

Class period. A collection of statistical data that enables these data to be represented and interpreted in an easier way.
