    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.
