Question

the circumference of a circle is 20π miles. what is the diameter? c = 20π mi give the exact answer in simplest form. miles

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: Substitute the given value

We are given that $C = 20\pi$. Substituting into $C=\pi d$, we get $20\pi=\pi d$.

Step3: Solve for the diameter

Divide both sides of the equation $20\pi=\pi d$ by $\pi$. So, $d = 20$.

Answer:

20
