Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements. Step 1 Learn the formulas relating radius to circumfe...
The radius is used to define the diameter, circumference, and area of the circle. The diameter of the circle is a straight line through the center point. So, the length of a diameter is given by twice the radius. That is, {eq}d = 2r {/eq}. Circles have an angle of {eq}2\pi...
from Chapter 14 / Lesson 5 253K Discover how to find the area and circumference of a circle. Learn the area of a circle formula, the circumference of a circle formula, how to calculate the circumference of a circle, and how to calculate the area of a circle. Related...
Now that we can easily calculate the circumference from either diameter or radius, we can use this formula to find the perimeter of a semi circle or arc length. Arc length can be explained as simply the length of a section of the boundary around a circle. When trying to find the circumfe...
