Area of a Circle Using Diameter | Formula & Examples from Chapter 1 / Lesson 8 149K Learn the formula for finding the area of a circle using the diameter with an applied example. Also, learn how to find the diameter and radius from the area. Related...
The area of a circle is calculated with the help of the formula: Area of circle = πr2. If the diameter is given we can find the radius by dividing the value of diameter by 2. After getting the radius, we can substitute its value in the formula: Area of circle = πr2to get the...
Circle area a = πr² Circle circumference c = 2πr Circle diameter d = 2r You can derive many other circle formulas from the above equations, which you'll find in the dedicated paragraphs below. If you're looking for the circle formula itself, check out this equation of a circle ca...

Radiusr, diameterd, and circumferencecare related.The higher the radius or the diameter, the higher the circumference. The circle length formula connects these variables in a single equation: c = 2πr If you only know the diameter, you can find the length of the radius of the circle by ...
Radius of Circle EquationThe radius of a circle equation on the cartesian plane with center (h, k) is given as (x − h)2 + (y − k)2 = r2. This is known as the equation of a circle when the radius is known. Here, (x, y) are the points on the circumference of the ...
