Question

the circumference of a circle is 5π kilometers. 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 $C = 5\pi$ kilometers, we substitute into the formula: $5\pi=\pi d$. Divide both sides by $\pi$. So, $d = 5$.

Answer:

5
