hello : 
the  radius is : d/2 = 6
the area of the circle is : A =π×r×r=3.14×6×6 = 113.04 

Answer:

Area = 113.04  square units.

Step-by-step explanation:

Given  : Diameter = 12.

To find : Find the area of the circle.

Solution : We have given diameter  = 12 .

Radius = [tex]\frac{diameter}{2}[/tex].

Radius = [tex]\frac{12}{2}[/tex].

Radius = 6 units.

Area  of circle = pi * (radius)².

Area  of circle = 3. 14 ( 6 )².

Area =  3. 14 * 36

Area = 113.04 square units.

Therefore, Area = 113.04  square units.
