To solve this you need to know that area, or "a" = [tex] \pi r ^{2}[/tex]. so, since the radius is 1/2 the diameter, it would be a =(3.14)(6)[tex] ^{2} [/tex], so 3.14x36. This = B, 113.04 sq in

d= 12 in
⇒ r= 12/2 in
⇒ r= 6 in.

S= r^2* π= 6^2*π= 36*π ≈ 113.04

The final answer is B. 113.04 sq. in~
