Question

circle o has a circumference of 36π cm. what is the length of the radius, r? 36 cm 72 cm 18 cm 6 cm

Explanation:

Step1: Recall the circumference formula

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

Step2: Substitute the given circumference

Given \(C = 36\pi\) cm, substitute into the formula: \(36\pi=2\pi r\).

Step3: Solve for \(r\)

Divide both sides of the equation by \(2\pi\). \(\frac{36\pi}{2\pi}=r\). Simplifying, \(r = 18\) cm.

Answer:

18 cm
