Question

the circumference of a circle is 11π m. find its radius, in meters.
answer attempt 1 out of 2
r = m

Explanation:

Step1: Recall 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 given value

We know that $C=11\pi$. So, $11\pi = 2\pi r$.

Step3: Solve for radius

Divide both sides of the equation by $2\pi$. $\frac{11\pi}{2\pi}=r$. The $\pi$ terms cancel out, and we get $r=\frac{11}{2}= 5.5$.

Answer:

$5.5$
