Why would you use a circle graph?
Why would you use a circle graph?
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
What are circle chart called?
pie chart
What tool is used to draw sectors on a circle graph?
A compass, also known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs.
How do you write the equation of a circle?
The equation of a circle appears as (x – h)2 + (y – v)2 = r2. This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the coordinates of the center of the circle being at the point (h, v), and r represents the radius.
Which explains how do you find the radius of a circle whose equation is in the form x2 y2 Z quizlet?
Which explains how to find the radius of a circle whose equation is in the form x2 + y2 = z? The radius is the square root of the constant term, z.

What is the equation for a circle centered at the origin?
The equation of a circle with center (h,k) and radius r is given by (x−h)2+(y−k)2=r2 . For a circle centered at the origin, this becomes the more familiar equation x2+y2=r2 .
What is the origin of circle?
Thus, using the theorem of Pythagoras, x2 + y2 = r2 , and this is the equation of a circle of radius r whose centre is the origin O(0, 0). The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .
