Mathematical Context
Circumference is often used in geometry and involves calculations.

To find the circle's area, you first need its circumference.
Measurements Involved
When discussing circumference, expect to use units of length like meters or inches.

What's the circumference of this field in meters?
Circle Specifics
Circumference is specific to round shapes; don't use it for squares or rectangles.

The circumference, not the width, dictates how much fence we need.

So the knowledge generates ignorance.

Quote examples
Frans de Waal
Dutch Scientist
Scientists are supposed to study animals in a totally objective fashion, similar to the way we inspect a rock or measure the circumference of a tree trunk. Emotions are not to interfere with the assessment. The animal-rights movement capitalizes on this perception, depicting scientists as devoid of compassion.

Quote examples
Charles Spurgeon
British Clergyman
Cast away your sloth, your lethargy, your coldness, or whatever interferes with your chaste and pure love for Christ, your soul's husband. Make Him the source, the center, and the circumference of all your soul's range of delight.

Quote examples
Margaret Atwood
Canadian Novelist
If you're put on a pedestal, you're supposed to behave yourself like a pedestal type of person. Pedestals actually have a limited circumference. Not much room to move around.

Quote examples
Laura Riding
American Poet
We live on the circumference of a hollow circle. We draw the circumference, like spiders, out of ourselves: it is all criticism of criticism.

Quote examples
Empedocles
Greek Philosopher
The nature of God is a circle of which the center is everywhere and the circumference is nowhere.

Quote examples
Blaise Pascal
French Philosopher
Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.

Quote examples
Baltasar Gracian
Spanish Philosopher
One must pass through the circumference of time before arriving at the center of opportunity.
