Question: What is the area of the circle? Write your answer using $\pi$. 11 mm Use the number pad to enter your answer in the box. The area of the circle is ____ mm².
1. **State the problem:** We need to find the area of a circle with radius $11$ mm.
2. **Formula:** The area $A$ of a circle is given by the formula $$A = \pi r^2$$ where $r$ is the radius.
3. **Substitute the radius:** Here, $r = 11$ mm, so
$$A = \pi \times 11^2$$
4. **Calculate the square:**
$$11^2 = 121$$
5. **Final expression:**
$$A = 121\pi$$
6. **Answer:** The area of the circle is $121\pi$ mm².
