What is the radius of a circle whose equation is x 2 y 2 6y 18 0?
4
The radius of the given circle is 4.
What is the radius of the circle x 2 y 2 6y 0 *?
So the radius of the circle is 7 units.
How do you find the radius from the circumference of a circle?
To find the radius from the circumference of a circle, you have to do the following:
- Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter.
- Divide the diameter by 2.
- There you go, you found the circle’s radius.
What is the area of a circle whose equation is x² y² 6x 8y?
The are of the circle given the equation is 25π sq.
What is the center of a circle whose equation is x 2 y 2 4x 8y 11 0?
(-2, 4)
The center of the circle of the given equation is x2 + y2 + 4x – 8y + 11 = 0 is (-2, 4).
What is the vertex of the parabola x2 4 y 2 )?
The vertex of the parabola is at (0, 2).
What are the center and radius of the circle defined by the equation x2 y2 6x 4y 4 0?
The center is =(3,−2) and the radius is =3. graph{(x^2+y^2-6x+4y+4)=0 [-14.08, 8.11, -5.51, 5.58]} Nam D. Jul 5, 2018.
What is the approximate length of radius r?
The approximate length of the radius r is 12 inches.
What is the equation for a circle with a radius of 64?
The equation for a circle is (x – h) 2 + (y – k) 2 = r 2, where (h,k) is the center of the circle and r is the radius. We can eliminate (x+3) + (y+2) = 4 and (x+3) 2 + (y+2) 2 = 64. The first equation does not square the terms in parentheses, and the second refers to a center of (-3,-2) rather than (3,2).
How to find the radius of a circle in the plane?
Find the radius of the circle whose center is O (2, 1), and the point P (5, 5) lies on the circumference. The equation of a circle in the cartesian plane is given by (x − h) 2 + (y − k) 2 = r 2.
What is the equation when the center of the circle is 0?
When the center of the circle is at origin (0,0), the equation of the circle reduces to x 2 + y 2 = r 2 The arc of the circle is the distance between two points along a section of a curve. The radius of the curve is the radius of the circle of which it is a part.
What is the general equation of a circle?
The general equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the location of the circle’s center, and r represents the length of its radius. Circle A first has the equation of (x – 4) 2 + (y + 3) 2 = 29. This means that its center must be located at (4, –3), and its radius is √29.
