Question

Is circumference cubed, squared, or just left alone?​

Answer 1

Circumference is a linear distance. So if the diameter is in feet, then the circumference is also in feet (not square feet or cubic feet)

-------------------------------------

Example:

Let's say we had a circle with diameter d = 10 feet

The circumference is approximately...

C = pi*d

C = 3.14*10

C = 31.4

The circumference is roughly 31.4 feet

The circumference is essentially the distance around the circle's edge. We can use a flexible ruler or a string to help measure out this distance, or you can imagine laying the circle's edge to be placed along a straight line, which is another way to help measure the perimeter.
