Answer 1

For your questions:

**Question 1:**
The diameter of a circle is the radius multiplied by **2** (though it appears that this option isn't provided). None of the provided responses (A 22, B 33, C 44) are correct.

**Question 2:**
If a circle has a radius of 3, the area is calculated using the formula \( \pi r^2 \). Thus, you would multiply \( \pi \) by \( 3^2 \), which is 9. However, since 9 is not in the options provided (A 66, B 99), neither response is correct.

**Question 3:**
Using the area formula \( A = \pi r^2 \) for a circle with a radius of 3:
- \( A = \pi (3^2) = \pi \times 9 \approx 28.26 \). Therefore, the correct response is **C 28.26**.

In summary:
- Question 1: No correct answer provided.
- Question 2: No correct answer provided.
- Question 3: **C 28.26**.
