Question

what is the circumference of a circle with a diameter of 21 feet? c = ? ft. do not round your answer. use 3.14 for pi (π). circumference formula c = πd

Explanation:

Step1: Identify the formula

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter.

Step2: Substitute the given value

Given $d = 21$ ft and $\pi=3.14$, we substitute into the formula: $C=3.14\times21$.

Step3: Calculate the result

$C = 65.94$ ft.

Answer:

$65.94$
