Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius.

Step2: Substitute values

Given $r = 9.4$ m and $\pi=3.14$, we have $A=3.14\times(9.4)^{2}$.

Step3: Calculate $(9.4)^{2}$

$(9.4)^{2}=9.4\times9.4 = 88.36$.

Step4: Multiply by $\pi$

$A = 3.14\times88.36=277.4504$ $m^{2}$.

Answer:

$277.4504$ $m^{2}$
