Step-by-step explanation:
1. The formual for this is 2πr2 where you time 2 times pi times the raduis times to I did get formual of the internate and I havent done surface area of circles for a long time so sorry if its wrong.
2- Questoin the anwser I belive is 76 Squared, because you add all the stuff up or cubes I mean and you get 76 now I sure you know that just when you label thhe flat end of a cube it must be squared because we are only dealing with surface area.
