Question

find the radius of a circle with a circumference of $28\pi$.

the radius is $\square$ units.

Explanation:

Step1: Recall circumference formula

The circumference $C$ of a circle is given by $C = 2\pi r$, where $r$ is the radius.

Step2: Substitute given circumference

Substitute $C = 28\pi$ into the formula:
$28\pi = 2\pi r$

Step3: Solve for $r$

Divide both sides by $2\pi$:
$r = \frac{28\pi}{2\pi} = 14$

Answer:

14
