What is the general form of a circle with center at (- 4 3 tangent to y-axis?

With center (-4,3),and the y-axis as a tangent,then, radius of circle us 4. (x + 4)^2 + (y – 3)^3 = 16.

What is the standard equation of a circle if the center is on the y-axis?

The equation of a circle with centre at (h, k) and radius equal to a, is (x – h)2 + (y – k)2 = a2. When the centre of a circle is on the y-axis i.e., h = 0.

How do you find the center and radius of an equation?

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being “r”. This form of the equation is helpful, since you can easily find the center and the radius.

What is the general form of the equation of a circle?

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

How do you find the tangent of a circle?

The tangent will have an equation in the form \\ (y = mx + c\\) so to find the equation you need to find the values of \\ (m\\) and \\ (c\\). First, find \\ (m\\), the gradient of the tangent. On a diagram, draw the circle and the tangent at the point P (3, -4) and draw the radius from the centre (0, 0) to the point P.

How do you find the center of a circle with radius?

With the radius at 2.5, the center of the circle on the y axis and the x axis being a tangent, we then know the center of the circle is at: (0,2.5) The equation for a circle is: (x −a)2 + (y − b)2 = r2 Where (a,b) is the center of the circle and r is the radius of the circle.

What is the center of a circle on the Y axis?

With the radius at 2.5, the center of the circle on the y axis and the x axis being a tangent, we then know the center of the circle is at: (0,2.5) Where (a,b) is the center of the circle and r is the radius of the circle.

What is the radius of a circle touching the x-axis?

Since the center is 6 above the center, the radius need to be 6 in order for the circle to touch the x-axis. Here is your equation: The Rock reveals the key to success for normal people.
