Question

find the area.
14 ft
a = ? ft²
a = πr²
use π = 3.14

Explanation:

Step1: Find the radius

The diameter is 14 ft. The radius \( r=\frac{14}{2}=7 \) ft.

Step2: Calculate the area

Use the formula \( A = \pi r^{2} \). Substitute \( r = 7 \) and \( \pi=3.14 \).
\( A=3.14\times7^{2}=3.14\times49 = 153.86 \) \(ft^{2}\).

Answer:

153.86
