Compute the circumference of a circle with radius 12 ft.

A. [tex] 24 \pi \, \text{ft} [/tex]
B. [tex] 144 \pi \, \text{ft} [/tex]
C. [tex] 24 \pi^2 \, \text{ft} [/tex]
D. [tex] 12 \pi \, \text{ft} [/tex]



Answer :

To compute the circumference of a circle, you can use the formula:
[tex]\[ C = 2 \pi r \][/tex]
where [tex]\( C \)[/tex] is the circumference and [tex]\( r \)[/tex] is the radius of the circle.

Given that the radius ([tex]\( r \)[/tex]) is 12 feet, we can substitute this value into the formula:

[tex]\[ C = 2 \pi (12) \][/tex]

Simplifying this we get:

[tex]\[ C = 24 \pi \text{ ft} \][/tex]

Therefore, the circumference of the circle is [tex]\( 24 \pi \text{ ft} \)[/tex].

Among the given options, the correct one is:

[tex]\[ 24 \pi \text{ ft} \][/tex]
