How do you write the equation of a circle given its radius and its center at the origin What about if the center is at H?

How do you write the equation of a circle given its radius and its center at the origin What about if the center is at H?

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

What is the equation of circle with Centre H K and radius r is?

The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .

What is the equation of a circle with center at the origin and radius r?

The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .

What is the equation of circle with Centre of origin and radius is 6 cm?

So, if the center is (0,0) and the radius is 6, an equation of the circle is: (x-0)2 + (y-0)2 = 62.

What is the equation of a circle with a center at the origin and a radius of 12?

The equation of a circle with center (h,k) and radius r is given by (x−h)2+(y−k)2=r2 . For a circle centered at the origin, this becomes the more familiar equation x2+y2=r2 .

What is the equation of a circle with center at the origin and a radius of 5?

x2+y2=5.

Which point is on the circle centered at the origin with a radius of 5 units distance formula?

Which point is on the circle centered at the origin with a radius of 5 units? Distance formula: StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot. A.

What is the formula of shortest distance?

Using the Distance Formula , the shortest distance between the point and the circle is |√(x1)2+(y1)2−r | .

Which equation represents a circle with a center?

In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.

What is the shortest distance from a point to a line?

segment perpendicular

Which axis is closer to the point 5 7?

The y-coordinate is -7. So, a=5 and b=-7. The distance of the point P(5,-7) from the y-axis = |5| = 5 units. Therefore, the distance of the point (5,-7) from y-axis is 5 units.

What is the distance of the point Q 5’7 from Y axis?

The x-coordinate of the point P is 5. The y-coordinate of the point P is 7. Hence, the perpendicular distance of the point P from the y-axis is 5 units.

What is the distance of the Point 2 7 from Y axis?

Answer: Therefore, distance of (2,7) from y-axis is 2 units. So, x coordinate is 2 and y coordinate is 7. So distance of P from y axis is 2 units and distance of P from x axis is 7 units.

What is the distance of Point 7 from Y axis?

Answer: Step-by-step explanation: The distance of points A(5,–7) from y-axis = 5 units. Therefore, The distance of points A(5,–7) from y-axis = 5 units.

What is the distance of the point (- 6 7 from the y axis?

Solution : The distance of point P(a,b) from the x-axis is given by y-coordinate of the point. Therefore, the distance of point (-6,7) from x axis is 7 unit.

What is the distance of the point A 7 3 from Y axis?

The distance of point a(7,3) from y axis is 7.

What is the distance of point P 3 7 from Y axis?

The x-coordinate is 3. The y-coordinate is 7. So, a=3 and b=7. The distance of the point P(3,7) from the x-axis = |7| = 7 units.
