# How do you write a circle in standard form?

## How do you write a circle in standard form?

The standard form of a circle’s equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.

What is the standard equation of circle?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

### What is the standard form of a circle example?

Solution: Equation for a circle in standard form is written as: (x – x1 )2 + (y – y1 )2 = r2. Here, (x1 , y1 ) = (2, -3) is the center of the circle and radius r = 3. (x – 2)2 + (y + 3)2 = 9 is the required standard form of the equation of the given circle.

What does H stand for in H k )?

What does “h” stand for in (h,k)? h is the radius of the circle.

## How do I write an equation in standard form?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

How do you find the standard equation?

### What is decimal standard form?

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

What is K in circle?
