Question

find the area. 12 ft a =? ft² a = πr² use π = 3.14

Explanation:

Step1: Identify the radius

The radius $r = 12$ ft.

Step2: Apply the area - formula

The formula for the area of a circle is $A=\pi r^{2}$. Substitute $r = 12$ ft and $\pi=3.14$ into the formula: $A = 3.14\times12^{2}$.

Step3: Calculate $12^{2}$

$12^{2}=12\times12 = 144$.

Step4: Multiply by $\pi$

$A=3.14\times144 = 452.16$ $ft^{2}$.

Answer:

$452.16$
