The equation of a circle is (x - 4)² + (y - 3)² = 25. What's the center of the circle
For a unit circle, this distance is 1 unit, or the radius is 1 unit. Let us learn the equation of the unit circle, and understand the ways to represent each of the points on the circumference of the unit circle, with the help of T-ratios....
What is the equation of a circle? The equation of a circle is a mathematical representation that describes all the points on a circle's circumference. It is written in the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the center of the ci...

In geometry, a circle is a set of points in a plane that are a given distance from a given point in a plane. The circumference is defined as the linear distance around a circle. The diameter of a circle is the distance from the circle through th...
What is the approximate radius of the circle whose equation is (x-√3)^2+(y+2)^2=11? ( ) A. (x-√3)^2+(y+2)^2=11 B. (x-√3)^2+(y+2)^2=11 C. (x-√3)^2+(y+2)^2=11 D. (x-√3)^2+(y+2)^2=11 E. (x-√3)^2+(y+2)^2=11...
Setting this equal to the total area we calculated:πR2=289π Step 5: Simplify the equationWe can divide both sides of the equation by π (assuming π≠0):R2=289 Step 6: Solve for RTaking the square root of both sides gives us:R=√289=17cm Thus, the radius of the circle is 17...
