Question

circle o has a circumference of 88π cm. what is the length of the radius of the circle? \boxed{} cm

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute given circumference

We know \( C = 88\pi \), so substitute into the formula: \( 88\pi = 2\pi r \).

Step3: Solve for \( r \)

Divide both sides by \( 2\pi \): \( r=\frac{88\pi}{2\pi} \). The \( \pi \) terms cancel, and \( \frac{88}{2}=44 \), so \( r = 44 \).

Answer:

44
