What is the center and diameter of a circle when x2 plus y2 equals 12x -10y -12?

If: x^2 +y^2 = 12x -10y -12
Then: x^2 +y^2 -12x +10y +12 = 0
Completing the squares: (x-6)^2 +(y+5)^2 = 49 which is the radius squared
Center of circle: (6, -5)
Diameter of circle: 14 units

well it means that if u square something that's is all i know
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
The diameter of a wheel is 50ft how do i find the distance around it 8 times?
The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet
What is the center and the radius of the circle x2 plus y2 -4x -6y -3 equals 0?
Equation of circle: x^2 +y^2 -4x -6y -3 = 0 Completing the squares: (x-2)^2 +(y-3)^2 = 16 square units Therefore center of circle is at (2, 3) and its radius is 4 units
How do you find the circumference of a semi-circle?
The length (circumference) of the curved part of a semi-circle is pi times the radius (pi*R). If the diameter is given, then the semi-circle length is 1/2 (pi * x D) because the radius is 1/2 of the diameter.(There are 2pi radians in a full circle.)A closed shape formed from a semi-circle has a perimeter P = D + (pi * D / 2)(diameter plus the curved part)
