a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. the length of such a line. any radial or radiating part.
The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle.
To find the radius from the circumference of a circle, you have to do the following:
To find the radius, divide the area by pi, then take the square root.
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
The General Form of the equation of a circle is x + y + 2gx +2fy + c = 0. The centre of the circle is (-g, -f) and the radius is √(g + f - c). Completing the square. Given a circle in the general form you can complete the square to change it into the standard form.
What does "h" stand for in (h,k)? h is the radius of the circle.
Find slope by finding the difference in the y points, and divide that by the difference in the x points.
Gradient is another word for "slope". The higher the gradient of a graph at a point, the steeper the line is at that point. A negative gradient means that the line slopes downwards.

So when x is minus 2 the left end of the line. What will y be well we just need to substitute thisMoreSo when x is minus 2 the left end of the line. What will y be well we just need to substitute this minus two into the equation well y is equal to half times minus two so half times minus two plus one.
How to Find The Domain and Range of an Equation? To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
When referring to an Internet address or name, a domain or domain name is the location of a website. For example, the domain name "google.com" points to the IP address "216.58. 216.164". Generally, it's easier to remember a name rather than a long string of numbers.
Consider the relation {(0,7),(0,8),(1,7),(1,8),(1,9),(2,10)} . Here, the relation is given as a set of ordered pairs. The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} .
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.
