The radius of a circle is 7. What is the area?

Answer

To find the area of a circle given its radius, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the radius of the circle**:
The radius (r) of the circle is given as 7.

2. **Recall the formula for the area of a circle**:
The formula to calculate the area (A) of a circle is:
\[ A = \pi r^2 \]
where \( \pi \) (pi) is a constant approximately equal to 3.14, and \( r \) is the radius.

3. **Substitute the radius into the formula**:
Now, substitute the value of the radius into the area formula:
\[ A = \pi (7)^2 \]

4. **Calculate \( 7^2 \)**:
Calculate the square of the radius:
\[ 7^2 = 49 \]

5. **Multiply by \( \pi \)**:
Now, substitute \( 49 \) back into the area formula:
\[ A = \pi \times 49 \]

6. **Write the final answer**:
Therefore, the area of the circle is:
\[ A = 49\pi \]

### Final Answer:
The area of the circle with a radius of 7 is \( 49\pi \).
