The general equation for the circle - or one of them - is:
(x - a)^2 + (y - b)^2 = r^2
Where:
a and b are the coordinates of the center
r is the radius
Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
depending on the circles equation..a larger circle is easier
The equation of the circle is: (x+3.2)^2 +(y+2.1)^2 = 18.49

The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
To write an equation that includes the keyword "how to write an equation," you can use a variable like x to represent the phrase. For example, the equation could be x "how to write an equation."
The equation for calculating the area of a circle is A r2, where A represents the area and r is the radius of the circle.
This starts with the collocation circle to go through the three points on the curve. First write the equation of a circle. Then write three equations that force the collocation circle to go through the three points on the curve. Last, solve the equations for a, b, and r.
write a rule as an equation
(x - h)2 + (y - k)2 = r2 where h is the x coordinate of the center of the circle. where k is the y coordinate of the center of the circle. where x is the x coordinate of point (x,y) on the edge of the circle. where y is the y coordinate of point (x,y) on the edge of the circle.

Rewrite the above program so that the program accepts any value for the radius then recalculate the area of the circle.
The radius of a circle = the diameter of the circle divided by 2
