A 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 from the center to the circumference ...

where (a,b) is its center and r is its radius. Note that the equation given above is in the standard form for a circle, so we can easily identify both the center and the radius by comparing it to the standard equation. We all know what circles look like, so...
Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements. Step 1 Learn the formulas relating radius to circumfe...
The radius is any line segment from the center of the circle to any point on its circumference. In this case, ( r) is the distance between ( (2,7)) and ( (3,4)). ( r=√(10)) ( ((x-h))^2+((y-k))^2=r^2) is the equation form for a circle with ( r)radius...
Finding a common denominator (which is 8):72=288Thus:288+178=458 Step 8: Final equation of the circleNow, we can write the equation of the circle as:(x−34)2+(y+54)2=458 Step 9: Identify the center and radiusFrom the standard form (x−h)2+(y−k)2=r2:- The center (h...
