To find out the center and radius of a circle, first of all, convert the given equation into the center-radius form by completing the square in {eq}x {/eq} and {eq}y {/eq} variable and then compare it with the standard center-radius form of the circle. ...
Move ( -16) to the right side of the equation by adding ( 16) to both sides.( ((x+6))^2+((y+4))^2=-36+36+16)Simplify ( -36+36+16).( ((x+6))^2+((y+4))^2=16)This is the form of a circle. Use this form to determine the center and radius of the c...

Center and Radius of a CircleA circle is a flat geometry with a uniform rounded periphery. The periphery is known as the circumference of the circle. Each point on the circumference of a circle is equidistance from a fixed point called the center. And the distance ...
Standard Form of a Circle: The equation of a circle in standard form is (x−h)2+(y−k)2=r2, where (h,k) is the center of the circle and r is the radius of the circle. Center: The center of a circle is the point in the middle of the circle. ...
a在非典期间 我们最好不去人多的地方 In SARS period we most very go to human many places[translate] awhere f is the equation given in equation (2.2), and (xi,yi, zi) is the center of the ith sphere with radius ri.[translate]
Equation of a Circle in the Standard Form: A circle is the locus of infinite points surrounding a fixed point in such a way that it has a constant distance from that point. This constant distance is termed as theradiusof the circle and the fixed point is called the ...
in the central angle, where a denotes the orbit radius, R is the Earth radius, and d is the satellite distance from the station. Upon combining Eqs. (10) and (11), the fractional observation density \(\nu \) can be computed as a function of the boresight angle \(\theta \). When...
Determine the center and radius of a circle given that its equation is {eq}x^2 - 2x + y^2 - 20y = -100 {/eq}. Use exact values. Circle: Circles are two-dimensional geometric shapes consisting of points equidistant from a fixed point in spa...
