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)
Radius of circle: 12/2 = 6 units
The circumference of a circle if the radius is 12 equals about 75.4
The center of the rectangle to the corner of the rectangle is the radius of the circle. That can be found using the distance formula sqrt((5/2)^2+(12/2)^2) = 6.5 = r 5/2 is half the height of the rectangle and 12/2 is half the height of the rectangle. radius = 6.5
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.
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 center of (3, 10) passing through (12, 12) then the radius is the square root of 85 which is about 9.2195 rounded to four decimal places.
