Review the standard and expanded forms of circle equations, and solve problems concerning them.

And so with that information, I want you to pause the video and see if you can figure out the equation for this circle. Alright, let's work through this together.

The standard form of the equation for a circle is: (x-h)^2 + (y-k)^2 = r^2 where (h, k) is the center of the circle and r is the radius of the circle. This is based on the distance formula where we …

In the standard equation of a circle, -k would be the y-value of the center of the circle while -h would be the x-value of the center of the circle. Note the negative on h and k, and if k or h are …

Standard equation of a circle Learn Features of a circle from its standard equation Graphing a circle from its standard equation

A circle has a radius of 37 units and is centered at (1.3, 3.5) . Write the equation of this circle.

Given the standard form equation of a circle, graph the circle. For example, graph the circle whose equation is (x+5)²+ (y+2)²=4.

You don't 'turn' that equation into a circle with radius 5 and center (0,0)... it already is that circle. The general form for the equation of a circle is: (x-h)^2 + (y-k)^2 = r^2 is the equation of a …

To find the area of a circle, we can use the following formula: Area of circle = π × radius 2

The easiest strategy is to plug in the values you know into the circumference formula (in your case, plug in circumference). Then, solve for r by manipulating the equation. This way you …
