Question

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

Explanation:

Step1: Find the radius

The diameter $d = 14$ ft, and the radius $r=\frac{d}{2}=\frac{14}{2}=7$ ft.

Step2: Calculate the area

Using the formula $A = \pi r^{2}$, with $\pi = 3.14$ and $r = 7$ ft, we have $A=3.14\times7^{2}=3.14\times49 = 153.86$ ft².

Answer:

$153.86$ ft²
