How can I derive the formula for circumference and how can it be used?

The formula for circumference is: C = 2πr   or   C = πd

Step-by-step explanation:

C = 2πr

(Circumference equals two times pi times radius)

C = πd

(Circumference equals pi times diameter)

Circumference is the distance around a circle.

Diameter is the measure of one side of the circle to the other.

Radius is half of the diameter.

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
