To calculate the area of a circle, you can use the formula:
\[ A = \pi r^2 \]
In this case, you've provided a diameter of 5 ft. To find the radius \( r \), you need to divide the diameter by 2:
\[ r = \frac{5 \text{ ft}}{2} = 2.5 \text{ ft} \]
Now plug the radius into the area formula using \( \pi \approx 3.14 \):
\[ A = 3.14 \times (2.5 \text{ ft})^2 \]
Calculating \( (2.5)^2 \):
\[ (2.5)^2 = 6.25 \]
Now multiply by \( 3.14 \):
\[ A = 3.14 \times 6.25 = 19.625 \]
Now rounding to the nearest hundredth:
\[ A \approx 19.63 , \text{ft}^2 \]
So, the area of the circle is approximately:
\[ A = 19.63 , \text{ft}^2 \]
