What does it mean to write a number in standard form?
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.

What is the difference between expanded and standard form?
Expanded notation can be defined as a way of expressing numbers by showing the value of each digit. Writing a number in expanded notation is not the same as writing in expanded form. The original form of the number ‘234’ is called a standard form.
Can a be 0 in standard form?
The advantage of standard form is that it accommodates both horizontal lines (A=0) and vertical lines (B=0) . The disadvantage is that A,B, and C do not stand for anything obvious (like the slope or y -intercept ).

Is circle a function?
If you are looking at a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.21. jan 2015.

Do you find area?
To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
How do I measure a circle?
This distance is called the radius of the circle, or r for short. And any line segment from one point on the circle through the center to another point on the circle is called a diameter, or d for short. Note: Because 2 x r is the same as the diameter, you also can write the formula as C = π x d.
What is circle of radius?
In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
How do you measure the diameter of a circle with a ruler?
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
What is circumference measured in?
The circumference of a circle is measured in meters, kilometers, yards, inches, etc. There are two ways of finding the perimeter or circumference of a circle. The first formula involves using the radius, and the second involves using the diameter of a circle.

What is half the circumference of a circle called?
An arc is part of the circumference of a circle. If the arc is over half of the circumference then it is called a major arc. If it is less than half of the circumference it is called a minor arc. The diameter cuts the circle exactly in half and goes through the centre.
