The formula for the circumference of a circle is .
Plug in our given values and solve.
Example Question #52 : Geometry
What is the circumference of a circle with a radius of ?
To find the circumference of a circle, use the equation:
Substitute the given value for the radius into the equation:
Example Question #53 : Geometry
An ant is standing at the center of a perfectly circular plate. If the ant crawled in a straight line, he would have to crawl 6 inches to reach the edge of the plate. How many inches would he crawl if he crawled a full circle around the edge of the plate?
We need to find the circumference:
In this formula stands for the radius and stands for the diameter.
The distance the ant must crawl to the edge from the center is the radius of the circle.
Plug in 6 inches for :
Example Question #54 : Geometry
If a circle has a radius of meters, what is its circumference?
The formula for the circumference of a circle is , where is the diameter. This can also be written as , where is the radius of the circle. We were given the radius, so we take the second formula and plug in for .
