well you would times that by: R2=D*3.14(pie)=C
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
(x - h)2 + (y - v)2 = r2
The answer is indeterminate. For example, if the equation is of the form x2 - 2ax + y2 - 2by = 25, all that can be said of the radius of the circle is that it is greater than 5.
I assume you mean (x-7)^2 + (y + 6)^2 = 100 (using "^" for powers). Answers.com eliminates some signs, such as the equal sign. This equation is in a form in which you can (almost) read off this information directly. A circle with equation (x - a)^2 + (y - b)^2 = r^2 has a center (a, b), and a radius of "r". In this case, just convert the original equation to: (x - 7)^2 + (y - (-6))^2 = 10^2 And you can directly read off the coordinates of the center (7, -6), and of the radius (10).
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
The Pythagorean theorem is used to develop the equation of the circle. This is because a triangle can be drawn with the radius and any other adjacent line in the circle.
You should increase the radius in the standard equation of a circle centered at the origin. The general form is ( x^2 + y^2 = r^2 ), where ( r ) is the radius. By increasing ( r ), you extend the distance from the center to any point on the circle, making it larger.
(x - h)2 + (y - v)2 = r2
(x-2)^2 +(y-3)^2 = 16
The answer is indeterminate. For example, if the equation is of the form x2 - 2ax + y2 - 2by = 25, all that can be said of the radius of the circle is that it is greater than 5.
There are different standard forms for different things. There is a standard form for scientific notation. There is a standard form for the equation of a line, circle, ellipse, hyperbola and so on.

There are probably several ways to approach it; one general equation for the circle is: (x - a)2 + (y - b)2 = r2 This describes a circle with center at coordinates (a, b), and with a radius of r.
