Question

In Exercises 31–40, write the standard form of the equation of the circle with the given center and radius. Center (0, 0), r = 7

Accepted Answer

for a circle with the following center and radius finance equation. In standard form our center is 00 and our radius is 23. So let's look at the standard form of circle. The standard form a circle is given by x minus H squared plus y minus k squared equals r squared. Where h comma K. Is our center, our is our radius. It's going to plug in our values into its formula R H. We notice is equal to zero, The K is also equal to zero and VR. is equal to 23 plugged us into our equation. We get x minus zero squared plus y minus zero squared equals 23 squared. Now we can simplify it and farther X zero. That's just x squared. Why minus zero? Just y squared And 23 squared is 529. Because you can't simplify this any farther. The answer is X squared plus y squared Equals 529. Just makes the answer to our problem answer B. Okay. I hope I hope you solve the problem. Thank you for watching. Goodbye.
