$\huge\boxed{113.04}$

Diameter ( $d$ ) is equal to twice the radius ( $r$ ). So, find the radius by dividing $\frac{12}{2}$ . The radius, or $r$ , is $6$ .

Substitute in the value. $A=3.14*6^2$

Follow the order of operations and solve the exponent first. $A=3.14*36$

Multiply. $A=\boxed{113.04}$
