Or a circle with the following center radius. Find this equation and center and radius form and graph center equals negative 11 13 and R is equal to 17. We know the center of a circle is the point H K. The standard radius form is the same as the standard form of a circle, which means we can write our center radius form as X minus H squared plus Y minus K squared S equals to R squared. Now we notice our H will be negative 11. So we have X minus negative 11 squared or X plus 11 squared, Y minus 13 squared will be next. And finally R squared. Now R squared will be 17 squared which should be 89. We now have the equation of our circle X plus 11 squared plus Y minus 13 squared equals to 89. If we look at our equations and possible graphs, we can determine the answer to our problem is graph D OK. I hope to help you solve the problem. Thank you for watching. Goodbye.
