Question

what is the circumference of the circle below? 6 ft

Explanation:

Step1: Identify the radius

The radius \( r \) of the circle is given as \( 6 \) ft.

Step2: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \) (or \( C=\pi d \), where \( d \) is the diameter; since \( d = 2r \), both formulas are equivalent).

Step3: Substitute the radius into the formula

Substitute \( r = 6 \) into \( C = 2\pi r \):
\( C = 2\times\pi\times6 \)
\( C = 12\pi \)

If we use \( \pi\approx3.14 \), then:
\( C\approx12\times3.14 = 37.68 \) ft.

Answer:

The circumference of the circle is \( 12\pi \) feet (or approximately \( 37.68 \) feet).
