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
What is circle times circle equals square AND circle triangle divided by square equals circle plus circle?
well it means that if u square something that's is all i know
What is the centre and radius of the circle x squared plus y squared plus 10x -14y plus 10 equals 0?
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
What is the length of tangent line from -2 3 to the point of contact with the circle x2 plus y2 plus 6x plus 10y minus 2 equals 0?
Equation of circle: x^2 +y^2 +6x +10y -2 = 0 Completing the squares: (x+3)^2 +(y+5)^2 = 36 Radius of circle: 6 Center of circle: (-3, -5) Distance from (-2, 3) to (-3, -5) is sq rt of 65 which is hypotenuse of a right triangle Using Pythagoras' theorem: square root of 65^2 -6^2 = 29 Therefore length of tangent line is the square root of 29 Note that the tangent line of any circle always meets its radius at right angles which is 90 degrees.
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
