Find the radius( r) for the circle. 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 equa...
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,k) is (34,−54)- The radius r is √458=3√54 Final Answer...

A circle is a flat surface bounded by a circumference whose points are equidistant from the center. The area is the part that is inside and, we can calculate it by multiplying the irrational number pi by the radius squared. We can establish the general equatio...
Properties of a Circle A circle is a round, symmetrical shape with no corners or sharp edges where each point along its edge is equidistant from the center. A circle has many properties, such as the radius, diameter, circumference, and area. ...
Notice what you already know about the circle. If you are expected tofind the radius, you will already know the diameter, area or circumference. Choose the equation from step 1 that relates radius to the quantity you already know. Step 3 ...
Step 3: Identify the Center and RadiusFrom the equation (x+p2)2+(y+p2)2=(p√2)2, we can identify:- Center: (−p2,−p2)- Radius: p√2 Step 4: Write the Parametric EquationsThe parametric equations for a circle with center (h,k) and radius r are given by:x=h+rcosθy=k...
