What is the equation of a circle with a radius of 6?
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 the circle with a radius of 4 and a center at?
4=√(−2−x2)2+(3−y2)2 .
What is the equation of a circle that has the center of (- 3/5 and radius of 6?
Answer: The equation of the circle, can be given as (x + 3)2 + (y + 5)2 = 36. Explanation: Given, center coordinates = (-3, -5) and radius = 6 units.
What is the equation of a circle with Centre of origin and radius is 6cm?
∴ The required equation of the circle is x2 + y2 – 36 = 0.
What is the radius of a circle whose center is at (- 6 7 and is tangent to the y axis?
With center (-6,7), tangent to the y-axis Because the circle is tangent to the y-axis, then the radius is 6 because it’s the distance from the center to the y-axis.
How do you find the equation of a circle with the center?
The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .
How do you find the equation of a circle given the center?
Example. x 2 + y 2 + 2 g x + 2 f y + c = 0 is used to work out the centre of the circle, and the radius. ( x − a ) 2 + ( y − b ) 2 = r 2 is used to write the equation of the circle when you know the centre and the radius.
What is the equation of the circle with a radius of 4 and a center at 0 0?
x2+y2=4.
How would determine the equation of a circle given the radius and the center at the origin 0 0 )? What about if the center is not at the origin?
If the center of a circle is (0, 0), then the equation of the circle is of the form x^2+y^2=r^2, where r is the radius. The radius of a circle is the distance from the center of the circle to the edge of the circle.
Which equation represents a circle with a center at (- 4 9?
Summary: The equation which represents a circle with a center at (-4, 9) and a diameter of 10 units is (x + 4)2 + (y – 9)2 = 25.
What is the equation of the circle with center 6 9 and radius 3?
The circle has a center at (5,5) and a radius of 2. Therefore, the equation is (x-5)2+(y-5)2=22, or (x-5)2+(y-5)2=4.
How do you find the equation of a circle with center?
The equation of circle with (h,k) center and r radius is given by: (x-h) 2 + (y-k) 2 = r 2. Thus, if we know the coordinates of the center of the circle and its radius as well, we can easily find its equation. Example: Say point (1,2) is the center of the circle and radius is equal to 4
What is the formula to find the radius of a circle?
Therefore, the radius of a circle is CP. By using distance formula, (x-h) 2 + (y-k) 2 = CP 2. Let radius be ‘a’. Therefore, the equation of the circle with centre (h, k) and the radius ‘ a’ is, (x-h) 2 +(y-k) 2 = a 2. which is called the standard form for the equation of a circle. Equation of a Circle in General Form
How do you find the square root of a circle equation?
1 . Input circle equation in standard or in general form. 2 . You can input integers ( 10 ), decimals ( 10.2 ), fractions ( 10/3) and Square Roots – (use letter ‘r’ as a square root symbol). Example: 2r3 = 2 ⋅ 3 = 0 NOTE: To input square root symbol type letter ‘r’.
What is the circumference of a circle equal to?
The circumference of a circle is equal to 2 (pi) of radius or pi of diameter. The area of a circle is equal to the pi of radius-squared. What is the equation of a circle when the center is at the origin?
