To find the circumference and area of a circle, we can use the following formulas:
1. **Circumference (\(C\))**:
\[
C = 2 \pi r
\]
2. **Area (\(A\))**:
\[
A = \pi r^2
\]
Given that the radius \(r\) is 2 ft and using \(\pi \approx 3.14\):
1. **Calculating the Circumference**:
\[
C = 2 \times 3.14 \times 2 = 12.56 \, \text{ft}
\]
2. **Calculating the Area**:
\[
A = 3.14 \times (2^2) = 3.14 \times 4 = 12.56 \, \text{ft}^2
\]
Thus, the circumference of the circle is \(12.56 \, \text{ft}\) and the area is \(12.56 \, \text{ft}^2\).
