center (3,0) radius 12
So the equation is
(x-3)^2 + y^2 = 144
→ y^2 + x^2 - 6x - 135 = 0
in general a circle of radius r centered at (h, k) has the equation:
(x - h)^2 + (y - k)^2 = r^2
Equation of circle: x^2 +y^2 = 12x-10y-12 Completing the squares: (x-6)^2 +(y+5)^2 = 49 So center of circle is at (6, -5) and its radius is 7 units
The radius is sqrt(12) = 3.464 (rounded)
The term "radius of 6" typically refers to the distance from the center of a circle or sphere to its edge, which is 6 units. In a circle, this means that any point on the circumference is 6 units away from the center. The diameter of this circle would then be 12 units, as the diameter is twice the radius.
Radius of circle: 12/2 = 6 units
The circumference of a circle if the radius is 12 equals about 75.4
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
(x-3)2+y2=144
(x-3)^2-(y-3)^2=(12)^2
Equation of circle: x^2 +y^2 = 12x-10y-12 Completing the squares: (x-6)^2 +(y+5)^2 = 49 So center of circle is at (6, -5) and its radius is 7 units
The radius is sqrt(12) = 3.464 (rounded)
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
If you mean x^2 +y^2 = 144 then the radius of the circle is 12 units
x2 + y2 =144
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
The term "radius of 6" typically refers to the distance from the center of a circle or sphere to its edge, which is 6 units. In a circle, this means that any point on the circumference is 6 units away from the center. The diameter of this circle would then be 12 units, as the diameter is twice the radius.
The circumference of a circle if the radius is 12 equals about 75.4
Radius of circle: 12/2 = 6 units
