Equation: x^2 + y^2 +10x -14y +10 = 0
Completing the squares: (x+5)^2 + (y-7) -25-49 +10 = 0
So: (x+5)^2 + (y-7) = 64
Therfore the circle's centre is at (-5, 7) and its radius is 8

How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is the radius of a circle with a area of 35 mm squared?
The radius of a circle with an area of 35 mm squared is 3.34mm
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
What is the formula for the surface area of a circle?
The formula for the surface area of a circle is pi times the square of the radius. It is represented as A equals pi times r squared.
Area of a circle with 2 inch diameter?
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
What is the centre and radius of a circle when x squared plus y squared -2ax -2ay equals 0?
The centre is (a, a) and the radius is a*sqrt(2).
How do you solve x squared plus y squared equals 13?
The equation describes a circle with its centre at the origin and radius = √13. Each and every point on that circle is a solution.
Is the area of a circle is twice the radius?
Area equals pi times the radius squared.
What is the center and radius of the circle of x squared plus y squared -4x -6y -3 equals 0 enscribed on the Cartesiian plane?
x2+y2-4x-6y-3 = 0 Using the appropriate formula it works out as:- Centre of circle: (2, 3) Radius of circle: 4.
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
What does pi numbers mean?
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
What is area of a circle if circumference equals pi divided by 2?
Area of a circle is: pi times radius squared
How is pi used to determine the area of a circle?
Area of a circle equals pi (3.14) times the radius squared.
What is the centre and radius of a circle on the Cartesian plane when x squared plus y squared -4x -2y -4 equals 0?
If: x^2+y^2 -4x -2y -4 = 0 Then by completing the squares of x and y: (x-2)^2+(y-1)^2 = 9 Therefore the centre of the circle is at (2, 1) and its radius is 3 units
How do you graph x squared plus y squared equals 36?
The graph is a circle with a radius of 6, centered at the origin.
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is the area of an 0.8 cm circle?
If 0.8cm is the radius (distance from the centre to the edge of the circle) of the circle, the area of the circle is 2.010619298 cm squared. If 0.8cm is the diameter (distance from one side of the circle to the other), the circle's area is 0.5026548246cm squared.
