The area is $196 π$ $196pi$ , or $615.752160$ $615.752160$ when evaluated to 6 decimal places.

There is an equation for the area of a circle:

$A = π r^{2}$ $A=pir^2$

Where $A$ $A$ is the area and $r$ $r$ is the radius. $π$ $pi$ is $π$ $pi$ , it is its own number. Plugging in the radius stated we can evaluate:

$A = π {(14)}^{2}$ $A=pi(14)^2$

$A = 196 π$ $color(green)(A=196pi)$

If we write out $π$ $pi$ and evaluate with an (un)reasonable amount of decimal places:

$π ≅ 3.1415926536$ $pi~=3.1415926536$

$A = 196 \times (3.1415926536)$ $A=196xx(3.1415926536)$

$A ≅ 615.752160$ $color(green)(A~=615.752160)$

The area of the circle is $615.75$ $615.75$ units $^{2}$ $""^2$

Area of a circle is defined with this equation: $A = π r^{2}$ $A=pir^2$

When $r = 14$ $r=14$ ,

$A = π {(14)}^{2}$ $A=pi(14)^2$
$A = 615.75$ $color(white)(A)=615.75$ units $^{2}$ $""^2$
