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.

I hope this helps!

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
