(x - 4)2 + (y - 0)2 = 102
or x2 - 8x + 16 + y2 = 100
or x2 - 8x + y2 - 84 = 0
The centre is (3,-1) and the radius is sqrt(10).
x² + y² = 100.
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).
If the centre of the circle is at the point (a, b), the equation is: (x - a)2+ (y - b)2= 100.
The radius will depend on the plus or minus value of 10 or whether or not it needs a plus sign but the center of the circle is at (-2, 3)
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
The centre is (3,-1) and the radius is sqrt(10).
Equation of a circle is given by: (x-a)2 + (y-b)2 = r2 Here a & b are the coordinates of the center. So, a = -3 & b = 6. And r = 10. Thus, the equation formed is (x+3)2+(y-6)2 = 102
The general formula: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius. So the required equation of the circle is: (x - -4)^2 + (y - 0)^2 = 10^2 (x + 4)^2 + y ^2 = 100
x² + y² = 100.

If the centre of the circle is at the point (a, b), the equation is: (x - a)2+ (y - b)2= 100.
The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.
The radius will depend on the plus or minus value of 10 or whether or not it needs a plus sign but the center of the circle is at (-2, 3)
If you mean (-3, 5) and (5, 11) then using the distance formula the radius of the circle is 10 units
The circumference of a circle can be found using the equation c=2πr. For example, if a circle has a radius of 10, its circumference is 20π, or 62.832.
Circumference = 2*Ï€*radius = 20*Ï€ feet
