The problem states: "The diameter of a circle is 11 m. Find its circumference in terms of π."

To find the circumference $C$ of a circle using its diameter, you use the formula:

$C = \pi \times d$

where $d$ is the diameter.

Given $d = 11 \, m$, the circumference in terms of $\pi$ is:

$C = 11\pi \, m$

So the answer is $11\pi \, m$.

Relative Questions

1. What is the relationship between radius and diameter?
2. How do you convert circumference to radius if given in terms of $\pi$?
3. What formula would you use to find the area of the circle given the diameter?
4. How does the formula change if you are given the radius instead of the diameter?
5. How would you express the circumference as a decimal if you substitute $\pi \approx 3.14$?

Tip

Always remember that the diameter is twice the radius: $d = 2r$.
