Q. Write the equation in standard form for the circle with radius 11 centered at the origin._____
Identify Center and Radius: We need to identify the center and the radius of the circle to write its equation in standard form. The standard form of a circle's equation is (x−h)2+(y−k)2=r2, where (h,k) is the center of the circle and r is its radius.Since the circle is centered at the origin, we have:h=0k=0r=11
Substitute Values: Now we substitute the values of h, k, and r into the standard form equation of a circle.(x−h)2+(y−k)2=r2Substituting h=0, k=0, and r=11, we get:(x−0)2+(y−0)2=112
Simplify Equation: Simplify the equation by squaring the radius and removing the zeros since subtracting zero does not change the value.x2+y2=121This is the equation of the circle in standard form.
