Question

the circumference of a circle is 15π centimeters. what is the diameter? give the exact answer in simplest form.

Explanation:

Step1: Recall the circumference formula

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

Step2: Solve for the diameter

Given $C = 11\pi$, we substitute into the formula $11\pi=\pi d$. Divide both sides by $\pi$: $d=\frac{11\pi}{\pi}=11$.

Answer:

11
