ANSWER FAST PLZ 25POINTS!!!!!!!!!!!

Answer:
B. 36[tex]\pi[/tex] square inches
Step-by-step explanation:
The area of a circle is: [tex]A=\pi r^2[/tex] , where r is the radius.
Here, we know the diameter is 12. We need to convert this to radius, so since the diameter is 2 times the radius, we know the radius must be 12/2 = 6.
So, the area is: [tex]A=\pi *6^2=36\pi[/tex]
The answer is thus B.
Hope this helps!
