Answer:
A
Step-by-step explanation:
The lateral surface area is given by pi*r*l, we can use trigonometry to find l. 8*sqrt(3)/l=sin(60), l=16 and r is given by tan(60)=8*sqrt(3)/r, r=8. The lateral surface area is 16*8*pi=128*pi
Well, I wasn't down in Georgia for my 7th grade, but my mom told me before that it helps you to see how your progress is. No need to be worried :) You've got this!
