The equation for lateral area is: 1/2 [( Pi x D) x Slant height) where D is diameter. We need to then find the slant height of the cone, which is a right triangle. $2^2+(2\sqrt3)^2=L^2$ L= 4 So $.5*(\pi*2)*4=A$ A=12.56

the answer choices are 8pi $4\sqrt{3}$$8\sqrt{3}$pi (this is after 8 square root of 3) and $8\sqrt{3}$ pi over 3.
