Concept explainers
To find: Therectangular equation of a circle of radius 8 centered at the origin.
Answer to Problem 4QR
The rectangular form of the circle is
Explanation of Solution
Given information:
Radius = 5
Center of the circle is at origin.
Formula used:
Rectangular form of a circle with center
Calculation:
Given that the center of the circle is at origin.
Thus, the coordinates of the center is
Now, find the rectangular form of the circle.
Substitute the value of radius and the coordinate of the center. Use the expression
Conclusion:
Hence, the required rectangular form of the circle is
