Question

circle o has a circumference of $88\pi$ cm. what is the length of the radius of the circle? □ cm

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 $C = 88\pi$ into the formula:
$88\pi = 2\pi r$

Step3: Solve for $r$

Divide both sides by $2\pi$:
$r = \frac{88\pi}{2\pi} = 44$

Answer:

44 cm
