A circle has a diameter of 24 ft . What is its circumference? Use 3.14 for π and do not round your answer. Be sure to include the correct unit in your answer.

The circumference of the circle that has a diameter of 24ft is .

Step-by-step explanation:

The circumference of a circle is given by the formula:

[1]

Where

is the circle's circumference.

. It is a constant and  represents the ratio between the length of the circumference to the diameter of the circle, that is, . This number is irrational and has infinite digits.

is the circle's radius.

The diameter of a circle is

ft

Therefore, we can rewrite equation [1] as  

Then

Using

Then, the circumference of the circle that has a diameter of 24ft is .

Notice that is dimensionless and, since the diameter is in ft the circumference is also represented in this unit.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
