Equation: x^2 +y^2 -10x +6y -15 = 0
Completing the squares: (x-5)^2 +(y+3)^2 -25 -9 -15 = 0
So: (x-5)^2 +(y+3)^2 = 49 which is the radius of the circle squared
Area of the circle: 49*pi = 154 square units rounded to the nearest integer

What is the area of the circle whose equation is (x - 9)2 (y - 3)2 64?
The 64 is equal to the radius squared. Therefore, 8 is the radius and the 9 and 3 are the coordinates of the center. Area of a circle is Pi * radius squared. In this case that is 64 times pi. or approximately 201.062
What is the equation of a circle whose center is at the origin and whose radius is 10?
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
What is the slope of the line whose equation is y - equals 0?
y = 0That's the equation of the x-axis.Its slope is zero.
What is the equation of the line that passes through 3 4 and is parallel to the whose equation is y equals 3x - 2?
y -4 = 3(x-3)y = 3x -5
What is the diameter of a circle whose area is 200.96?
The diameter of a circle whose area is 200.96 is: 16
What is the equation of a circle whose radius is 7 in?
General formula for a circle is X squared + Y squared = radius squared. So the answer would be x squared + y squared = 2.64575131 squared
What is the equation for a circle with its center at the origin and a tangent whose equation is y equals 7?
x2 + y2 = 49
What are the center and radius of the circle whose equation is 2x squared plus 2y squared -8x -12y -6 equals 0?
Divide all terms by 2 and complete the square for x and y:- So: (x-2)^2 + (y-3)^2 = 16 Therefore centre of circle is at (2, 3) and its radius is 4
How do you measure the area of a circle and why does it work?
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
What is the centre and radius of the circle whose equation is x squared plus y squared -4x -6y -3 equals 0 showing workings?
Equation: x^2 +y^2 -4x -6y -3 = 0 Completing the squares: (x-2)^2 + (y-3)^2 -4 -9 -3 = 0 So: (x-2)^2 +(y-3)^2 = 16 Therefore the centre of the circle is at (2, 3) and its radius is 4
What is the centre and radius of a circle whose equation is x squared plus y squared -4x -6y -3 equals 0 showing work?
Equation: x^2 +y^2 -4x -6y -3 = 0 Completing the squares: (x-2)^2 +(y-3)^2 -4 -9 -3 = 0 So: (x-2)^2 +(y-3) = 16 Therefore the centre of the circle is at (2, 3) and its radius is 4
What is the radius for a circle whose equation is x2 y2 16?
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
What is the area of the circle whose equation is (x - 9)2 (y - 3)2 64?
The 64 is equal to the radius squared. Therefore, 8 is the radius and the 9 and 3 are the coordinates of the center. Area of a circle is Pi * radius squared. In this case that is 64 times pi. or approximately 201.062
What is the radius of a circle whose area is 314 feet squared?
10 feet.
What is the area of a circle whose radius is 8 mm?
A=22/7x8mm squared
What is circumference of a circle whose area is 314 squared?
The circumference is 62.815 units.
What is the radius for a circle whose equation is x2 plus y2 16?
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
