Calculate equation of a circle
WebWrite the standard form of the equation of the circle with a radius of 9 and center. In the next example, the radius is not given. To calculate the radius, we use the Distance Formula with the two given points. Write the standard form of the equation of the circle with center that also contains the point. WebUsing the distance formula to find the distance between the two points I get ${\sqrt {(0)^2 + (9-1)^2}}$ which is 8, divided by 2 is 4. ... (0, 5)$ & the radius $4$. Probably you have done the mistake while finding out the equation of circle. The equation of the circle with the center $(0, 5)$ & the radius $4$ is written as follows $$(x-0)^2+(y ...
